Agenda item 1. Opening^ election of chairman, adoption of agenda
The Meeting was opened "by Mr. Schmidt on behalf of the IAEA. He
thanked the hosts at Karlsruhe for their hospitality and excellent organization of the meeting. He emphasized the growing importance of the Karlsruhe Charged Particle Group within the international nuclear data exchange.
This was well demonstrated by the charged-particle data handbook producedby the Pachinformationszentrum Karlsruhe from the KaChaPag EXPOR fileB to
be distributed later in the meeting.
Mr. Mttnzel, head of the Karlsruhe Charged-Particle Group, welcomed
the participants on behalf of Prof. BOhm of the Kernforschungszentrum
Karlsruhe*"*"* Rittberger mentioned in his opening remarks that numerical andfactual data banks become increasingly important but can be useful only
in close international cooperation.
Mr. Mflnzel was elected chairman of the meeting.
The tentative agenda was approved with some minor modifications (seethe preceding page).
Agenda item 2. Brief status reports of the Centres
Mr. Tabbs presented the Progress—Report of the MEA •fe'teBank, see
Appendix Q»w Jite illustrated the activity and position"'"o'!'"']lill3X-!5ij"in theframe world of its customers, other data centers and committees, by a flow
chart (working paper 2 ) . * He introduced the new Information pamphlet of
the NEA-DB (working paper 3 ) .
NEA-DB expects to transmit about 250 EXPOR entries per year from compilation of new experimental datar.however the current rate is 400 per year
due to_additional.' NEUDADA-EXFOR conversion. He explained the developmentof Computational Formats at NEA-DB (working paper 4)»
Mr. Abe presented the Status Report of the JaganeseStudy Group, see
Appendix $• They have now gained some experience' In" 'c'fW compilation in
NRDP-S format, which is in full operation for storage and retrieval. A
bibliographic list of the works compiled was submitted as working paper 10.
NRDP-2 is in structure and in many details similar to EXPOR, but there
is no automatic conversion from NRDP-2 to EXPOR or vice versa.
The meeting recommended to continue to study the compatibility between NRDF-2 and EXPOR; to encourage a Japanese participation in the international exchange of CPND by a NRDP/EXPOR conversion program} and to study
possible obstacles, in particular those data-types compiled in NRDP-2
that have not yet been defined in EXPOR. See Action 64.
Mr. Abe explained that organization and financing of a Japanese data
center are still uncertain.
*"Working papers" are not included in this document, except if an"Appendix" is referred to, A list of "working papers" submitted to themeeting can be found in Appendix 1«- 13 -

Mr. Manokhin presented the CJD Progress Report, see Appendix 3» The
transmission of CINDA entries ancHSxFOR data is continuing with a highdegree of completeness, although there are at present temporary difficulties due to the transition to a new computer of the type EC-10/33*
The development of a USSR evaluated neutron data library in ENDF/B
format is in progress, partly in cooperation with Dresden (Seeliger).
He announced that another evaluated data file (on Fu-241 by V. Konshin)has just "been transmitted. The meeting recognized the importance of thefact that USSR evaluations are now issued in ENDF/B format.
Mr. Chukreev presented the CAJaD Progress Report, see Appendix 2.
They transmit now in regular intervals Exfor tapes with CPND from the USSR.
The Exfor checkprogram received from Danford is used, and also Pamela
Attree's Exfor check program is used at the Moscow University. Calculationsof (p,xn) reactions are being performed.
He reported about the creation of a Photonuclear Data Center at the
Moscow University, which began to compile data in EXFOR format.
The meeting recognized this as an important development and recommended
the use of the EXFOR system for photonuclear data. See Actions 53 and 54»
Mr. Letmnel presented the NDS Progress Report, see Appendix 7« He
reminded the meeting to celebrate the 15th anniversary of CINDA as an international effort, and the 10th anniversary of EXFOR, which meanwhile developed
to a well-functioning system with a high degree of completeness and reliability. See the summary of the contents of Exfor on page 4 of Appendix 7*
He introduced the "Nuclear Data Newsletter" and the Documentation Series
W
IAEA-NDS-. . .w which had been started to improve the contacts and services
to customers.
Mr. Schmidt gave a review of past and forthcoming meetings and conferences, see the attachment to Appendix 7.
Mr. Pearl stein presented the Progress Report of the NNDC, see Appendix
9. A large variety of materials were presented in working™'papers 12-19,

The new versions of the Manual and Documentation of E N D P / B - 5 (ENDF-102
and ENDF-201) are in preparation and will have no restriction in distribution.
The meeting highly appreciated the release of these data.
Mr. Behrens presented the Status Report of PIZ. See Appendix 4, whichin particular gives a summary of several importanT'publications within theseries Physik Daten/Physics Data. See also working paper 20.
Later in the Meeting, the activities and services provided were demonstrated in an excursion to the FEZ building.
Mr. Mttnzel and Mr. Klewe-Nebenius presented the KaChaPaG Status Report.
KaChaPaG with a minimum of manpower, had increased the' ch'arged particle
EXPOR file to 1600 reactions (including some contributions from CAJaD and
NDS, not counting a TRANS tape just recently received fron NNDC). Prom thisfile KaChaPaG has started, in cooperation with PIZ,to produce a handbook on
charged particle reaction data, of which a first volume with 800 pages plus
a separate index volume was presented, published within the PIZ series•Physics Data1.
The meeting recognized this as a most impressive application of the
EXPOR system.
The activities of KaChaPaO were demonstrated later in the meetingby an excursion to the Kernforschungszentrura Karlsruhe, where also several
nuclear data measurement facilities were visited.
See Appendix 6 for the KaChaPaG Status Report to the Meeting.
Agenda item 3. Review of Actions from the last Meeting
The actions listed in the Summary Record of the 1978 NRDC were reviewed.
Those actions that were found to be continued, are included in the list ofactions in the present document.
Agenda item 4.

The EXFOR System

A Subcommittee was formed consisting of
Mr. Barrows
Mr. Bychkow
Mr. Johnston
Mr. KLewe-Nebenius
Mr. Lemmel
Ms. Pfennig
The Subcommittee discussed all pending EXPOR matters following theworking paper 23 submitted by Mr. Lemmel. Various additional items were
subsequently submitted by the other members of the Subcommittee. The conclusions are summarized in a separate chapter of this document (see Exfor
Conclusions on page 23) and in Actions 61—', 100.

Agenda item 5»

Customer services

The discussions concentrated on possible improvements of the Exforsystem for the "benefit of its users. It was reported that Prof. Vonach,
who uses Exfor data as a basis for data evaluation including covariancematrices, was not satisfied with the error information given in Exfor.
It was concluded to look into possibilities of introducing in Exfor
computer-intelligible error types (see Exfor Conclusion 32). Even if
more precise and computer-intelligible error definitions would intially beavailable only in a small fraction of Exfor data, this may nevertheless beof increasing value to Exfor customers.
It was however stressed that while improvements are desirable, it isalso essential to keep the Exfor system simple.
Mr. Cier jacks proposed direct discussions between compilers, experimenters and data users at the next NRDC Meeting. See Action 112.
14).

Edited Exfor Formats are now available at NDS and NNDC (working paper
NEA-I© now sends out data in EXFOR and no longer in HEUDADA format.

As Exfor was designed to be readable by educated center staff, edited
formats for external customers are indeed necessary.
Computation formats derived from Exfor data are now available or underdevelopment at several centers, which should continue to keep each otherinformed about their progress (Action 69). It was recognized that there
must be different computation formats for different purposes and data types(e.g. resonance-parameters compared to cross-sections), and that computation formats cannot be as flexible as to include all Exfor data withoutsome loss of infrequent information (such as unsymmetric errors).
Agenda item 6.

Future plans, relations to CODATA, etc.

Mr. Tabbs reports that generalized exchange formats for all types ofnumerical data are now being developed, with associated FORTRAN or PL1 programs, partly under the auspices of CODATA. Mr. Tabbs was asked to watch
such developments and to distribute relevant information (Action 26).
Agenda item 7«

Data Base Management Systems

Several centers have now Data Base Management Systems in operation.
After a brief exchange of experiences it was decided that the centers should
continue to keep each other informed about new developments (Action 24).
Agenda item 8. Nuclear Data Flagging in P U S
It was reported that INIS has started to use data flags to indicate
whether the paper referred to, contains numerical data. However, theseflags are not yet in general use which is needed before one can usefully
retrieve on these flags.

Agenda item 9»

Photonurlear Data

Mr. Chukreev reported about the creation of the Photonuclear Data Centerat the Moscow State University. This will compile data up to the thresholdof production of Pi—Mesons, concentrating" on photonuclear reaction data for
production of neutrons, protons and heavier nuclides. Mr. Chukreev will
maintain close contacts to the new center, and Mr. Manokhin is in contact
with them to render them assistance about the use of SXFOR.
Mr. Pearlstein reports on Mr. Puller*s Photonuclear Data Center at the
National Bureau of Standards in Washington. This center is not very muchcomputerized but it feeds essential data into the evaluated data files. Tt
maintains a photonuclear bibliography
to which the USSR probably alreadycontributes and should continue to do so.
NNDC had transmitted their version of Berman*s library of photoneutron
reactions, converted into EXPOR format. A new version of Berman's libraryis expected to be released soon. NNDC will convert this into up-to-date
EXPOR format and then transmit it to the other centers.
Spe Actions

51-54 about photonuclear data.

With respect to compiling photonuclear data into EXPOR, it was decided
that this should be done in separate series of accession-numbers (e.g. startingwith "M" for Moscow and "U" for NNDC). See EXPOR Conclusion No. 36.
Agenda item 10. .Nuclear Structure and Decay Data
Mr. Abe reports that the Japanese Study Group encounters interrelation
between differential CPND and NSDD, and between neutron polarization data
and NSDD. The Japanese NRDF system covers nuclear reaction data and NSDD,
and it is therefore difficult to use the EXPOR system.
Considering- this difficulty, it was found important, to have a NRDF/KXFOR
conversion program in operation at least for those reaction data that arecoded in both systems, in order that the EXPOR centers and the Japanese Study
Group can benefit from the data compiled in the other system.
Tt was emphasized that the US had two different systems in operation:
EXPOR (resp. the EXFOR-compatible CSISRS) for experimental nuclear reaction
data, andQfSDF for nuclear structure and decay data, and that this separation
appeared useful, despite of the existing interrelations among1 these data types.
ENSDP is documented in ORNL-5054 plus an NNDC report containing the computerindependent physics documentation. NNDC was requested to distribute this
ENSDP documentation (lotion 23).
It is expected that within the US the responsibility forFJJSDF and the"Nuclear Data Sheets" will be transferred to NNDC.

Agenda items 21-26. Meeting of Center Heads
The Meeting of the Center Heads took place in a session parallel tothe subgroup on EXPOR matters (see agenda items 4 and 43).
Some results of the Center Heads discussions were carried on in theplenary meeting, concerning in particular:—

the "Protocol" originally designed for the cooperation and commitments of the neutron data cen+eT&9 should now contain two separate
Sections: one for the technical matters of the EXPOR system, where
all NRDC»s are involved; and another on the commitments of theneutron data centers. See Actions lt 28, 29 and Appendix 12»—

distinction of the various data categories in EXPOR: see EXPOR
Conclusion 18/19.

—

quality of compilation and the scope and priorities of data aresummarized in various other parts of the Minutes, see in particular
agenda item 45•—

re specialists meetings see Actions 2—6 and 11—16. It was emphasizedthat the Data Centers should keep close contacts with Specialists
Meetings: to prepare data compilations and retrievals for suchmeetings, and to obtain feedback from such meetings. At Conferences
the Data Centers should aim at more publicity, in particular by meansof panels.

—

re the I98O KTRDC Meeting see Recommendations/Actions 111—114.

Mr. Pearlstein reported, that a workshop on fission spectrum data, held
at LA.SL in October 1978, recommended that fission spectrum data should becompiled at the data centers as a basis for subsequent analysis and evalua-'tion. See working paper 13 which can be found on page 20 of Appendix 9.
See also Action 81.

Agenda item 31* CPND Bibliography
Mr. Burrows reports on the 1979 edition of "The Bibliography of Integral
Charged Particle Nuclear Data" published by NNDC as BNL-NCS-5O64O. This
CINDA-type document was much appreciated by the meeting. It was agreed thatthe format and contents, the publication schedule and the distribution of thebibliography on magnetic tape was very satisfactory and should continue as
before. Mr. Burrows asked for assistance in detecting errors; Mr. Munzel
said that he had already sent some comments concerning minor items, butthat he was very satisfied with this CPND Bibliography, although its scope
was somewhat larger than that of KACHAPAG. See Actions 41-44.
Agenda item 32. CPND exchange
About the present status of the CPND EXPOR file see the first part in
the KACHAPAG Status Report (Appendix 6) and the statistics on page 4 ofAppendix 7. It was agreed that KACHAPAG should continue to maintain theraasier file for integral CPND.
KACHAPAG had no technical problems with CPND Trans-Tapes received from
NDS and CAJaD. The Trans-^Tape from NNDC was received only recently before
the meeting, so that comments on it were premature.
- 18 -

Minutes

Considering the growing1 size of the KACHAPAG master file, it was founddesirable that no longer the entire file be transmitted but rather onlyadditions and changes (Action 70)>
As KACHAPAG1s data scope is restricted to integral CPTTO, and as othercenters had started to compile integral and differential CPND, often in thesame EXFOR entry, the need arose for an easy computer-intelligible flagging
system for distinguishing between integral and differential CP1TD. This needcoincided with a similar need to distinguish between experimental andevaluated data in Exfor, and a corresponding scheme of flags was designed.
See EXFOR Conclusions 18-19»
Agenda item 33«

CPMD publications

During the Meeting the first copies of the KACHAPAG handbook for
integral CPND were distributed fresh from the press, which was produced by
PIZ from the KACHAPAG master file as Physik Daten/Physics Data 15-1. This
most impressive application of the EXPOR system requires some feedback to
the EXPOR compilers, in particular with respect to the style and structuringof the free text. See EXPOR Conclusion 30 and Action 71.
Mr. Mflnzel announced that this handbook of numerical ICPND will be
continued and supplemented by a graphical part with excitation functions.
Mr. Burrows reported that NNDC plans a "barn-book" for light—element
and neutron—source reactions including also positron reactions. Mr. Howerton
will soon bring out an evaluation of fusion—relevant reactions within his
UCRL-50400 series.
Agenda item 34 « CPND - Miscellaneous
M D C had prepared a compilation of presently known CPND activities invarious countries (Memo CP-C/55» which was a continuation and completion of
CP-D/8I). See Appendix 11. Participants were asked to check this list andto send corrections and additions (Action 45).
Agenda item 41*

CINDA

The Archival Issue CINDA-A was published in Spring 1979, continuing theliterature up to 1976. The question was discussed, what to do with eventual
corrections or supplements to CINDA-A.
It was concluded that the CINDA 79 Supplement book will be a Supplement
to the Spring issue CINDA 79 and will exclude supplements and corrections to
the Archival Issue* Such corrections and supplements will, however, beavailable by means of computer retrievals from the master file. (Aotion

1211It was noted that Cinda contains too many thermal neutron data that
relate to solid state physics rather than to thermal scattering law datafor reactor physics, which is the only type of such data accepted in Cinda.
(Actions 22 and 102).
For other CINDA matters see Actions 103 to 107«

Mr. Johnston reports on the CBTDA programming done, which includes arevised exchange procedure between NBA—DB and TODC, NWDG will now update
directly the area—1 part of CINDA. W3A—DB will continue to update areas
2—4, for which the new coverage file was now completed.
Agenda item4?. WRENDA
The chapter- about WRENDA of the TOS Status Report (Appendix 7t p. 7)
was presented as well as the draft of the introduction to WREFDA 79/80(meanwhile published as ITOC(SEC)-73).
In. the discussion about the use of WRETOA it was felt that thisdocument continues to be important for smaller and for developing countries,
as a country like the US has its own system of defining priorities for datameasu rement s.
Agenda item 43. EXFQR (neutron data matters)
The neutron data specific items of the EXFOR system were discussed by
the same EXFOR subgroup as formed for agenda item 4» The results are included in the "SXPOR Conclusions" and in the Actions 8i-]QQ,
Mr. Johnston reports that the conversion of the NEUDADA file into Exforwas nearly completed and most of the converted data were already transmitted.
There remains a tape of TTEUDADA data of USSR origin, which was sent to CJD
for conversion into EXPOR. NEA—DB already reviewed these data and removed
all of those which already existed in EXFOR. Therefore, the remaining data(about 200 data sets) represent real gaps in EXFOR.
Mr. Manokhin replies that this tape was just recently reviewed at CJD,
and that his staff was studying the NEUDADA format. He had noticed, however,that many of these data were old and some of the references not correct, sothat checking of the data will be difficult in several cases. However, CJD
will transmit the data in EXFOR as soon as possible. See IDxfor Conclusion 38
and Action 90»— — —Agenda item 44. Evaluated Data
Mr. Pearlstein announced the release of several parts of ENDF—B/5 andof the entire ETTDF-B/4 Library (see above under agenda item 2 ) . There wassome discussion about the covariances file associated to ENDF-B/5, °f which
the documentation would become available soon. The evaluators of the covariances require, that Exfor data are compiled with more accurate information
on errors, corrections and standards (MONITOR), as also discussed elsewherein the Minutes.
After the free release of E N D F / B — 4 it was questioned, whether the UKNDL
could now also be released. The main reason for the fact, that some partsof the UKNDL could not yet be distributed freely, was that it contained
E N D F / B - 4 data, for which the release was restricted, NEA—DB will contact
the pertinent UK authorities (Action 40a).

Mr, Manokhin announced, that USSR evaluatiens were now issued in ENDP/B
format, and some had already been transmitted (Pu—241 from Konshin)

Mr, Lemmel reported about the EXFOR—V—series which was devoted toimportant evaluated data that were not part of one of the established libraries.
He also reported about the Agency's coordinated research programme about theTnteroomparison of Actinide Neutron Nuclear Data Evaluations, The participantsfrom 9 countries had started to produce actinide evaluations, which NDS compiles
in an IAEA Nuclear Data Library for Actinides - INDL/A. The present statusof this library is documented in IAEA-NDS-12.
Compilations of various nuclear data libraries available at their centersw»re presented by NEA-DB and NDS.
Agenda item 45»

EXFOR: data exchange and experiences

The quality of the SXFOR TRANS tapes had much improved due to the increasing use of more sophisticated check programs. Errors encountered wereregularly communicated to the originating center, sometimes with the explicit
request of transmitting the corrected data. Therefore, there was no need to
discuss any specific point at the meeting, in addition to those items
mentioned in the "EXFOR Conclusions",
Mr, Schmidt then presented a paper by A.B. Smith entitled "Provisionof Compiled Neutron Data", dated 2 August 1978, (See working paper &£ = NDS
Memo 363)• It reviews the quality of data center services in various aspects:
1, Speed of Response:2,

no criticism,

Completeness of Data Piles: The completeness was found varying
but sometimelunacceptable.

In this respect, the meeting agreed that thr> oomoletenes?; of -XPCR har,irmch improved during the last, few years. The completeness checks made at
NDS, which had in the past shown serious gaps in important areas, recently
indicated satisfactory completeness.
3, Superseded Data Sets not always deleted:remove superseded data from the system.

Centers should

In this respect it was pointed out that EXPOR provides two mechanisms:
either to overwrite superseded data by their new version, or to keep superseded and revised data on file, however distinguishable by a person-intelligible
and computer—intelligible STATUS code. This way is preferred in certain
cases for valid reasons, and data requestors have the option to obtain retrievals including or excluding superseded data.
4, Units and Dimensionality:

Uniform dimensionality was preferred.

This problem is well known by the data—centers, and the need forderiving unified output formats from EXPOR is recognized at all centers andlargely taken care of, EXPOR, being an exchange format, had been kept flexible- 21 -

in order to be able to transmit even unusual data without difficulties, toreduce error sources at compilation time and to send out "author—proofs"
close to the authorls original. These principles of EXFOR were still
considered valid, and the production of output formats from EXPOR is considered
responsibility of each center according to its user needs.
5. Formats: simple user formats were requested.
This is well recognized by the centers, and several simple "computation
formats" exist or are under development. It is now the feeling that different"simple user formats" are required, such as the BNL—325 format for resonanceparameters, or others which serve as the basis for listing and plotting crosssections as function of energy.

can be regarded as solved by the advanced EXFOR system with its improved

9. Errors, and10.

Standards

are well recognized and were discussed at the meeting in detail. With respect
to errors compare also agenda item 5•&•In general, the neutron data centers are in a permanent dilemma resulting
from the limited manpower available:-

either to have a high degree of completeness and no backlog at thecost of a poorer analysis of corrections, errors, standards, method etc.

—

or to compile less data but with careful review of corrections, errors,
standards, method etc, including questions back to the author aboutsuch items missing in the publications.

The meeting agreed that at least top priority data, in particular
standards and recent precision measurements of other important data should becompiled in EXPOR with careful error specifications. The matter should be
discussed also with experimenters and evaluators possibly at the next NRDC
Meeting in Brookhaven.

EXFOR Conclusions

For items 1-26, the discussions followed the NDS Working Paper 23.
It should be noted that this Working Ffeiper emerged from personal recordsof H. Lemmel and therefore contains subjective remarks, some of whichwere superseded or clarified already before the meeting.
Items 27-40 were brought up by the other participants or arose
during the meeting.

1.

Reformatting of Dictionary 2
The proposal of CP-c/62 is adopted in principle. There remains an
Action to NNDC to revise the proposal of CP-C/62 with respect tothe following items:- on the proposed page VII.11 add explanations for the codes "OBS"and "OCODE+"— review carefully details of the proposed codes to be added in
Dictionary 2, in particular- change the expansion of "REACTION11 to (QUANTITY MEASURED)- check whether "RCODE" for the Keywords ASSUMED and MISC-COL and"OCODE" for the keyword STATUS are correct in view of the checkprogram envisaged by NNDC
After this review, NNDC will send the final revision to NDS for
inclusion in Dictionary 2.

2.

Re Dictionary 4
The Manual wording on page VII. 11a should read:
Dictionary 4« Type of referenceThis Dictionary has normal format except that cols 56-61 of the explanation field are reserved for the term "DICT n11 pointing to the dictionary number n which contains the reference codes to be used with thegiven reference-type. Cols 56-61 are blank when no dictionary applies.

3°

Nuclide checking, Diet. 27, short-living isomers
The proposal of CP-D/89 is adopted. The wording marked in this memoby two vertical lines is entered on page VII. 15a. In contrary to thestatement in CP-D/89 NDS can start immediately entering the new flagin Dictionary 27.
Mr. Johnston reported another example where the nuclide checking withrespect to the isomer extension may occasionally fail. When for differential data a light particle is coded in SF7, one would not expect- 23 -

- 2 -

an isomer coded in SP4 even if isomers were involved. - No solution
was found for this case, and it was accepted that nuclide checking
though useful in the majority of cases cannot be made perfect.

4.

Superheavy Elements
Action on CINDA centers to introduce in the CINDA file and in the
CINDA book programs the formalism agreed earlier for unnamed heavy
elements, and to keep each other informed about the implementation.
Action on all to continue to watch decisions by international bodies.
It was reported that IUPAC had recommended, though not adopted, asystem of 3-character element names. For reasons of format restrictions, these appear unrealistic for adoption in CINDA or Exfor.

5.

Lab Picti onary
Action on NNDC to propose a code for the lab mentioned in CP-B/29.
Action on Kachapag to correct the respective entry which, as there
was no response from NNDC, had to be coded with a preliminary adopted
lab code. (Note by editor: This matter was solved "by correspondence
in Jan.1980.)

6.

Reference Codinga.

The formalism of multiple reference- identifications in the formof
REFERENCE((....)=())

is permitted for reports with more than one report code, and fromnow on also for reports containing conference proceedings:((S,report-code)-(C,conf-code))In the Manual the wording of memo 4C-3/179 will be inserted inchapter VIII under REFERENCE/Reports. Under REFERENCE/Conference
the following wording will be added:
If a conference also has a report code, both may be given. However, the report code must come first. These multiple references
may be given within a set of parentheses connected by an = sign:
NOTE: The data centers should provide the users with an appropriate expansion of the conference code.
(Note added by editor: see Memo CP-c/68 where the same formalism
was proposed to be used also in other cases such as as-a report being at the same time a thesis;a journal article being at the same time a conference paper.

This proposal seems to be logical and an appropriate Manual
wording should be agreed* - After distribution of the Draft ofthese Minutes no objection was received, so that the moregeneral use of this formalism should be regarded as adopted.)- 24 -

EXFOR Concl.

The rule proposed in CP-D/84 saying that in reference subfields"which may have any content" commas and parentheses are excluded,i s adopted. I t should be added to the Manual in the way proposedin CP-D/84.

Reference; double j o u r n a l - i s s u e numbers
It was agreed that no special rules should be introduced for this case.
The wording in the Manual should follow the proposal of CP-D/84.

Reference; Manual wording for journals
The wording proposed in CP~D/84 was adopted.

10.

Status codesa.

Re WDRN conclusions were reached before the meeting and theDictionary and Manual were updated accordingly.

b.

The code NDD was adopted,
Action on HEA-DB to submit a Manual wording for the meaning oft h i s code.

Polarization fitting coefficients
The codes for Dictionaries 34 and 36 were adopted as proposed in
CP-c/63. However, the dimension codes are "B/SR" instead of "NO".
Action on NNDC to propose a revised Lexfor entry on this topic
avoiding the explicit REACTION product proposed earlier and to improvethe existing Lexfor entry on "Polarization".

11.

Average Resonance Parameters
It x^as agreed that the Manual entry for MOMENTUM should remain as it
is. That is, it is not required to specify £ for average level spacing. There is an action on T. Burrows to investigate the meaningof average level spacing when no angular momentum is given. The
Lexfor definition for "D" will be revised as to permit also "D" data
without specification of "£".

12.
It was agreed that there is need to code "Reaction Rate" data. The
coding as proposed in CP-C/64 was adopted.
The Lexfor entry on Reaction Rates as proposed in CP-D/82 page 4 wasadopted, however the prescribed coding must be revised to follow
CP-C/64.

- 413»Spectrum averaged data
The codes KT for spectrum temperature and EN-MEAN for the meanspectrum energy are added to Dictionary 24. The code EN-UJMMY is
kept; it will be used instead of EN-MEAN where the mean-spectrum is
not known.
The Lexfor entry for spectrum average must "be revised to include theprescription for use of KT, EN-MEAN, and EN-IUMMY. Also the entry
for Fission neutron-spectrum averaged cross sections should be modified
to be consistent with the modification of spectrum average.

14«

Energies of gamma—lines
The proposal on this topic contained in CP-D/82 page 2 was not
accepted and was withdrawn. It will be clarified in the dictionary
24 that the column heading E may define energy values of a continuous
spectrum as well as discrete energies of gamma lines. Explanation
can be given in the BIB-Section under EN-SEC.

14a..

Quantum Numbers
It was noted that spin, parity and angular momentum column—headings
as presently coded in Exfor, currently refer only to nuclear resonances.
Spins and parities of excited levels should be quoted in free text.
Mr. Bychkov mentioned, that in the case of neutron scattering theseterms may be needed also for levels of the residual nucleus. Whensuch data are to be coded in Exfor, a corresponding Lexfor entry should
be submitted.
These statements should be added in Lexfor under "Quantum Numbers".

15»

Excited States
After discussion, the proposals in CP-A/14 and CP-c/66 were withdrawn.
The general conclusions weres
1.

The branch code "PAR" combined with the keyword "EN-SEC" provides
an adequate description of excited states.

2.

The use of a different formalism to describe excited states compared to metastable states would cause confusion.

P. Johnston pointed out that the coding string under the REACTION
keyword should not be considered the only place to describe thereaction in detail.
(Note by editor. See Memo CP—C/68, which recommends: If data areto be coded which cannot be uniquely specified by REACTION and
EN-SEC, the discussion should be reopened; such data should not be
coded into the present format with only free text explanation. )- 26 -

Flagging of Different Data Types
Re: CP-B/30 (Discrimination between integral/differential data)
CP-C/59 (inclusion of evaluated data into EXFOR)(similar proposal in CP-A/13)
It was concluded to introduce a flag on both the ENTRY and SUBENTRY
level to easy search for and discrimination between different datatypes in addition to the already existing discrimination of incident
particles by accession number series.

a.

CPND, NND, Photo-ND w i l l be discriminated by differing centeri d e n t i f i c a t i o n s as well as d i f f e r i n g entrynumber s e r i e s (Partly
modified l a t e r i n the meeting, see item 36.) They will be maintained and transmitted on separate f i l e s / t a p e s .

- recommended data
(RECJ6M i n REACTION SF9): »R« i n c o l . 42
- 27 -

- 6Other possible flags will be introduced as necessity arises.
These flags are inserted by the originating centers. Kachapag
vail insert the flags for all already transmitted CPND entries
to be included into its file.
Item b. will be added in the Manual on page III.5 under ENTRY - N3.
Item c. will be added in the Manual on page III.6 under SUBENT - N3.
(Note by editor. Memo CP-C/68 indicates that field N3 of the ENTRY
record is used by NNDC internally. Until the time that NNDC will
have adjusted their programs, any flags in N3 of neutron data entries
will continue to be considered as free text. It is understood that
NNDC will start using these flags for CPND.
As pointed out in CP-B/31, the use of 'D' flags as describedabove, implies that a subentry must not contain both differential andintegral data. A 'D' flag in the SUBENT record of subentry 001 meansthat all subentries of the entry contain differential data. )20.

Half-lives
In the case that NDS continues to compile cross—section relevant
half-lives in Exfor (presently Exfor-D6 series), these should be
removed from the D-series. They may eventually be included in theV—series. Kachapag is interested in receiving such entries in listing form.

21.

Nuclear Quantities
It was decided that the nuclear quantities compiled in neutronExfor continue to be coded in the form described in the beginningof memo CP-D/87. In the Manual it is added in chapter VIII
under REACTTON/Reaction Product, that this is another case where
the Reaction Product is not coded in SF4«
Action to all neutron data centers to review their nuclear—quantity
entries in particular whether the correct nucleus has been entered,and eventually correct them. Based on this experience, proposals
for more specific intructions for compilers to be included in Exforwould be welcome.
In the Lexfor entry "Nuclear Quantities" the following is added:"Subentries with nuclear quantities should, if applicable,
obtain the STATUS code (DEP accession-number) where theaccession number refers to the subentry containing thereaction data from which the nuclear quantity was derived".
This new rule is not obligatory for already existing entries.

22.

Gamma and particle multiplicity
The proposal of CP-C/61 is adopted. The definitions and coding of
nu-bar and eta as well as the Lexfor entry "Neutron Yield'1 should
remain unchanged.
A new Lexfor entry "Multiplicity" should be formulated on the basisof CP-c/61- 28 -

- 7-

EXFOR Concl.

— with a cross reference to "Neutron Yield"— with the rule added that "tMLT,N" is used only
in case of non-neutron induced reactions— with explanation added to define the term"partial multiplicity".
Action on NNDC to propose a final wording for this Lexfor entry.

23*

Asymmetry
NNDC noticed that the previous use of ASY in Exfor often agreed with
the Lexfor entry on polarization, but that this code was also used
for "asymmetry of fission fragments".
Action on NDS to review Dictionary 41 and eventually correct it.
The code ASY should be reserved to cases related to polarization.
Action on NDS to formulate a proposal for coding the asymmetry offission fragments.

24.

Decay Flag under PART-PET
Action; Kachapag will include in the next TRANS tape an entry withdecay flags entered under PART-DET, this being an example which cannot
conveniently be coded without this formalism.
Action on receiving centers to review this entry and eventually
approve the formalism of decay-flags under the keyword PART-DET. *)25«

R—Matrix Resonance—Parameters
Action on NNDC to supplement their very good Lexfor entries on
Resonance—Parameters by a chapter on the R-Matrix Resonance Parameters introduced by NNDC earlier.
Action on NDS to update the explanation of the corresponding quantity
codes in the Dictionaries accordingly.

26.

Distribution of CP-Memos
Memo CP-D/78 on this topic was adopted. Subsequently it was suggested
to increase the distribution by including also Prof. Ishkhanov, Headof Photonuclear Data Center, Centr Dannykh Fotojad. Eksp., NauchnoIss. Inst. Jad. Piz., Moskovskij Gos. Universitet, Leninskije Gory,
Moskva, USSR.

*) Note by editor: Memo CP-B/31 mentioned that in TRANS B008 a sample
entry of this type was included and that no response was received.
Kachapag therefore assumes that no centre had problems with thisformalism. It is therefore hoped that the matter is solved.

- 29 -

- 8-

The following items were discussed in addition to those mentionedin Working Document 23«

27»

Multiple Monitors
The case presented by NNDC in Working Paper 2? was recognized as acase presently not foreseen in Exfor.
It was emphasized that the coding of Monitors is very essential forthe purpose of automatized renormalization data. It was decided however, that cases as complex as the one presented, will not be suitable
for automatized renormalization, and that therefore it is sufficient
to code such cases in free text if a coding is not possible within
the present rules. It was agreed that the present rules should not
be changed.

28*

Forbidden combinations of Keywords
It was found that the computer programs at the NND centers are notdisturbed if old and new keywords show up together in the same subentry. Therefore page VIII.5 of the Manual about "Forbidden Keyword
combinations" is cancelled. Some corresponding changes may be needed
elsewhere in chapter VIII.
For retransmissions of old entries it remains desirable that theseare fully converted to up-to-date Exfor. However, for practicalreasons, corrections of old Exfor entries resulting in a mixture ofold and new keywords are acceptable.

29*

Spin Projection Data
Re CP-D/71 it was agreed that such data may be compiled in Exfor,
with the REACTION specification supplemented in free text.
(Note by editor:
clarification.)30.

See comment in Memo CP-C/68 requesting further

Text editing
Mr. Klewe reported that for the printed version of Kachapag it isdesirable to edit the free text of Exfor, which is limited to 55
characters per line, to longer lines. This is easily possible except
for cases where the "free text" in Exfor is structured. Consequently, Kachapag will develop a mechanism to flag such structured text
in order to exclude it from the editing mentioned above.
Action on Kachapag to communicate to the other centers their solutionof the matter. The other centers feeding into the Kachapag master
file may then proceed in the same way if they so decide.

EXPOR Concl.

Ion charges for fission—products
New data may demand a new column heading for ion charges of fissionproducts. Proposals should "be submitted whenever a center wishes tocompile such data.

32.

Error analysis
Action on all to instruct their Exfor compilers to continue to give
great care to compiling complete information on CORRECTION and ERRANALYS, for the benefit of data userst in particular data evaluators.
Compilers should also be encouraged to add comments drawing the attention of Exfor users to any deficiencies in the quality of the data,
if such information is available to the compiler.
It was recognized, that in view of the improving data processing facilities, it becomes more and more desirable to make the definition oferror-types computer-intelligible, in particular with respect to systematic or statistical errors, and whether 1, 2 or 3 standard deviations are meant. A possible formalism could be:
ERR-ANALYS (DATA-ERR1,1SIG,STAT) free text
(DATA-ERR2,1SIG,SYST) free text
It was recognized that such computer-intelligible error definition
would be possible only in a small fraction of the cases, however,this may nevertheless be useful.
Action on all to consider this item, eventually try out practicalexamples at their centers and submit proposals.
It was also suggested that eventually a computer—intelligible flag
could be introduced as a warning in case of data that should not be
used without consideration of special remarks given in the free text.
It was found desirable that important remarks on the quality of thedata should be given in a more standardized position of the BIB-Section,
as they can be found presently under REACTION, CORRECTION, ERR-ANALYS,STATUS, COMENT, METHOD and elsewhere. However no solution was found.

33.

Feedback from evaluators
Action on all to encourage compilers to include in Exfor c r i t i c a lremarks on the Exfor data by evaluators.
Several possibilities are given:- to use the keyword REL-REP- to add the evaluator's revision of the data in the free text
but leaving the original DATA Section unchanged- to add an additional subentry containing the evaluator's
revision, using the existing pair of STATUS codes OUTDT,RNORM
If different evaluators came to different results, of course bothcan be mentioned.

Dictionary 41
None of the NND centers intends a systematic conversion of old ISOQUANT entries to REACTION formalism. This requires that dictionary

the f i l e s .

NSDD
The principle was recognized that those NSDD that exist in Exfor are
only in support of the reaction data.

38.

USSR NEUDADA data
Action on CJD to compile in Exfor from the USSR NEUDADA data received
from NEA-DB, those which are still important.
It was recognized that some of these data are old and can perhaps not
be verified any more. In this case the data can eventually be taken
as given in NEUDADA, using the STATUS code NDD.
It was noticed that some of the references in NEUDADA were wrong
and that these data would probably be dropped.

EXFOR Concl.

Raw data
Action on NNDC to communicate in a CP-Memo their practice of headings at the top of raw data files supplementary to the Exfor data.
Eventually one could then agree on a common format for such headings,
which would make storage, retrieval and correlation of such datawith Exfor easier.
Centers are encouraged to store "raw" data, according to the rules
given in Lexfor under "NODATA" and "Raw Data".

40.

CFND TRANS tapes
The centers receiving Kachapag tapes expressed their preference toreceive, instead of the complete Kachapag file, only the entries
that are new or revised since the last transmission.
Action on Kachapag to aim at implementing this, and to inform centerswhen they are ready.
Only at a later stage Kachapag will investigate to change over totape transmission procedures identical to those among NND Centers.
Page IX. 3 of the Manual must "be kept up-to-date as matters develop.

41.

Reaction Product-Add in the Manual in chapter VIII under REACTION/Reaction Productto the definition of the Reaction Product:"In the case of two reaction products with equal mass, that one
with larger Z i s considered as the "heavier" product to "beconsidered as "Reaction Product" in SP4".

1. After the last NRDC Meeting in Paris (June 1978)
GJD transmitted to other centres magnetic tapes TRANS 4033 4035 containing 64 entries, and magnetic tape with thecorrected entries from TRANS 4029-4031. 130 works are in theprocess of compiling. The number of the works transmitted
is 80% of the number of the works to be compiled,
2. CJD completes the work on a development of the evaluated data library of the threshold (n,p), (n,-^-), (n,2n)reactions for all stable isotopes in the incident neutronenergy range from the threshold up to 20 MeV. A descriptionof the evaluation for nuclei with Z^20 including theexcitation function curves and the tables of the recommended
cross sections for the 14-15 MeV incident neutron energy havebeen published in "Nuclear Constants" (Issues 1(32), 2(33)>3(34) of current year).
3. A new version of the evaluated nuclear data file fornatural iron (File number 2012) has been developed in cooperation with the Physics Section of the Technical University
of Dresden. A description of the evaluation will be publishedin "Nuclear Constants".
4» CJD together with other coworkes from PJ5I carriedout the work on the determination of nuclear data requirements
for the transactinide burn-up and build-up calculations infast reactors*
5* In CJD as before a great attention was paid to thedevelopment of theoretical methods of cross section calculations. A new method of the description and systematinationof nuclear level densities has been developed. The level density modification influence on nuclear cross sections of various reactions have been investigated. A nev/ method of description of the hard part of the neutron spectra from the(n,n')>(p»n) reactions in terms of the direct process theory
has also been proposed.

Introduction

As you may know the Fachinformationszentrum is something like a National Information
Center responsible for the field of energy, physics and mathematics. Data compilationand evaluation is, therefore, only a part of our activities. These activities indata compilation and evaluation are, on the other hand, directed to the whole fieldof physics and to some special fields of energy. Because of the scope of this meeting
I will, however, restrict myself to those topics which are of relevance for the
discussion here.

3. Bibliography of Existing Data Compilations
As mentioned under 2 a further supplement (Physics Data issue 3-3 1978) has been
issued to this worldwide survey of all existing physics data compilations, andanother supplement is in print.

A. Charged Particle Reaction Data Compilation
A printed version (Physics Data 15, 1979) of the Kachapag Charged Particle Data
Compilation (Institut fur Radiochemie of the nuclear research center) has been
published in the meantime. A corresponding computer routine for. the phototype
setting of the data from the Exfor format has been developed for that purpose.

5. The Evaluated Nuclear Structure Data File (ENSDF)
The contribution of the Fachinformationszentrum Energie, Physik, Mathematik to theinternational collaboration in the evaluation of nuclear structure data (ENSDF) was
earlier reported. In the meantime the data on mass chain A = 86 have been published(J.W. Tepel, Nuclear Data Sheets ^5_ (1978) 553) and on two further chains, viz. A = 84
and 87 are in print and are to appear in Nuclear Data Sheets. Data on three further
mass chains, viz. A = 85, 91 and 92 have been completed.

The bibliographic data file associated with ENSDF, the "Nuclear Structure References"of NSR, is implemented on our computer and enables us to decode references appearing
in the ENSDF-file. The programmes needed for this operation were developed.

Several data analysis programmes (ADINF, LEVINF, OLGA) were developed at the Fachinformationszentrum Energie, Physik, Mathematik and programmes from Oak Ridge (MEDLIST,ANCOR, ADOPFIT, COMPARE, DATACK, GBRANCH, TRANLOC) were adapted to our Siemens 7.76o
installation.

Status ReportofJapanese Study Grouptothe Fourth Consultants' Meeting of NRDC
Karlsruhe, 8-13 October, 1979.

1.

Data compilation has been started by the use of NRDF-2,
which is a strage and retrieval system designed for CPND.

2.

The plan of the Study Group is to compile CPND produced inJapan, as mentioned in the status report of 1976.

As thefirst step the Study Group will compile those published inrecent six years since 1973 to 1978.

"Atomic Data andNuclear Data Tables" and "Nuclear Data Sheets" are used forthe survey of the data as well as the annual reports from
active institutions.

Thus the data file includes not only

CPND published in scientific journals but also those
appearing in the internal reports.
3.

As for the formers the Study Group compiled 57% of themat the end of September 1979.

It will cover 70% at theend of 1979
4.

The source data coded in NRDF format will be available
in the form of MT on the demand of the data center or thealternatives, but not of individual persons.

A transformation

program from NRDF-2 to the Generalized EXFOR and vice versa
is not yet available.

It will be prepared after summari2ing

discussion of the compilation experiences at an appropriate
occasion.

Activities of CPND compilation are not yet put on a firmbase, although efforts to establish Japanese data centerfor CPND are eagerly continued to the government.

KaChaPaG

KaCHaPaG Status Report

1. Compilations
During the last year the charged particle reaction file has grown up to
about 1600 reactions from which about 150 originated from CaJad/Moscow
and about 140 from NDS/Vienna. From these, about 50 new reactions weretransmitted in TRANS A002 and about 130 in TRANS D002 + D003. KaChaPaG
himself added about 500 new reactions since the last meeting.
it should be mentioned that the recently transmitted entries from CaJaD
and NDS are not yet included in the master file, since they contain several
subentries with differential data. In our last memo, we proposed a procedure
how to include these subentries into the file by adding a flag for easy
identification. If there is no general agreement to this proposal, we
should discuss the problem at this meeting to find a solution.
Two transtapes have been sent out according to the usual schedule.
During the last half year the output of compilations was slightly reduced,
since our group was and is strongly involved in- preparing the printed version of the KaChaPaG-file,- preparations for the planned graphical representation- investigations about the systematics of excitation functions,- preparing the new edition of the Karlsruhe Chart of Nuclides,
all without additional manpower. With the beginning of 1980, however, an
additional full-time compiler will be available due to the help of theFachinformationszentrum; thus, a real improvement of the manpower situation
is expected.
2. EXFOR_Sy.stem
Due to the Paris agreements to the most important pending problems, fortunately the situation in the EXFOR system was in our opinion relaxed during
the last year. As far as we see, there are only minor problems at leastfrom the charged particle point of view which still have to be discussed or
are yet pending.
However, some trouble arises from the fact that there is no completed andunified version of the manual available. We are yet working with two fromtime to time supplemented versions of this very important tool.

- 57 -

- 2-

The preparation of the printed version of our ICPND file has grown up in
the last months to nearly a full time job. A lot of bigger and smaller
problems had to be solved preventing us from getting finished within theplanned time. In the meantime, the index-volume is ready and the first datasheet volume containing 380 sheets will be presented on this conference,
I hope tomorrow. The second volume with further 400 sheets is in print andwill be available within the next 4 weeks.

4. Book of Diagrams
A lot of time has been spent in the past with internal discussions andpreparatory work for our planned book of diagrams i.e. an extensive graphicalpresentation of excitation functions and their systematics. I want to givea short impression of the goal of this compilation as we see it up to now.
In our opinion it is not sufficient for a large percentage of users of crosssection compilations to be provided only with the anyway restricted set ofexperimental data, even if all of them would have been compiled. There will
always remain a lot of gaps for which experimental data are missing, by what
reason ever. These gaps should be filled at least by any kind of predictions
which can provide the user whith an idea of what he should expect when planning
an experiment with an unknown reaction. Thus, the final goal of this graphicalcompilation will be to provide experimental and predicted excitation
functions for aiVl_ reactions which are physically and practically reasonable.
The basis for all kinds of systematic predictions is a most general and goodquality set of experimental data. One of our basic intentions, when we started
ICPND-compilations at KaChaPaG, was, therefore, to make these data available
for our future work on systematics.
The extrapolation to unknown data sets can be performed on several stages ofquality and effort. A lower stage is a systematic extrapolation by means ofa simple heuristic parametrization for position and shape of the excitation
functions. A more sophistcated procedure makes use of theoretical models
describing the physics contained in the respective reaction mechanism.
This topic is now under study, while the first more simple procedure wasmainly applied in the earlier systematics published in Landolt-BSrnstein.
As we feel, the project of publishing such an universal compilation of
measured and predicted reaction data must be performed in several stages.
The final goal, however, will certainly be reached only within several
years.

Staff

A few months ago, NDS could celebrate its 15th anniversary, when
the Nuclear Data Group, started by Carl Westcott end of 1963 with Kim
Ekberg and Eva Kiovsky, was called the Nuclear Data Unit after hiringin 1964 P« M. Attree, H. D. Lemmel and soon after Francoise Hirschbichler.
The years 1978/79 saw considerable staff fluctuations in the Nuclear
Data Section, involving also two of our longest—serving staff. In summer
1978 Fran<yoise Hirschbichler left and could be replaced only one year laterby Henrietta Hendrickson from the Reactor Shielding Information Center(RSIC), USA. In the meantime Necmi Day Day, a new physicist from Turkey,
took care of the data requests. End of 1978 Merkury Vlasov left theSection. He was replaced by Nikolai Kocherov from Leningrad. The newprogramme component of Atomic and Molecular Data for Fusion is expected
to be finally approved by the end of 1979 with the consequence that one
professional post will have to be transferred from the Nuclear Reaction
Data Unit to the new Unit; as this post was anyway already frozen for alonger period, this change will have no serious consequences.
A significant change occurred in the Computer Unit of NDS, where
due to an uncorrelated coincidence of events Pamela Attree, head of theUnit since the inception of the Agency's nuclear data programme, and theprogramme analysts Peter Smith and Hernan Marin-Guzman left and took positions in IAEA Safeguards and UNIDO. Two of these three posts will befilled in the near future, the third is being advertised. *)

CINDA

This year we are celebrating the 15th anniversary of Cinda as aninternational cooperation, though Prof. Goldstein's card file from which
Cinda emerged, is considerably older. In 1964i a duplicate of the US
Cinda file was established at Saclay, and Vienna transmitted its first
few hundred Cinda entries, soon after followed by entries made in Obninsk.
This year's Archival Issue of Cinda represents a respectable monumentfor 15 years of fruitful cooperation.
3.

Cinda work at NDS

The Cinda operations continued smoothly and routinely (G. Lammer).
Within the NDS working routines, the Cinda and Exfor operations are fully
integrated with respect to current awareness and coverage of new literature.
NDS received the Cinda file from Saclay four times a year and used
it for retrievals for internal purposes and occasionally for externalcustomers.
*) Note added in proof: Meanwhile two posts were filled by D. Cullen(head of the Unit) and M. Seits.

The current Cinda work of area 3 is up-to-date. At the moment,
however, the Agency's library is out of operation due to its move tothe new HQ, but the resulting delay is expected to be minor and easy
to overcome.
For the large scale coverage control, we are now using NEA—DB's ZZ
file, keeping our own paper files only for about the last year and not
for all report series, tfe would therefore like to request NEA-DB to send
us a complete listing of all ZZ entries - or a tape - regularly, e.g.,after each 'first' Cinda deadline. After the latest batch of ZZ entries
will have been transmitted from NDS, the area 3 and 4 ZZ file can beassumed to be complete and up-to-date.

4«

CINDA improvement program (GL)The cleanup of area 3 Cinda entries for the archival issue had
been completed by January 1979* Apart from obvious errors which could
be corrected on the basis of the existing entries, the original literature was consulted in various cases, e.g. for dubious entries, such as:
unusual isotopes, unusual energy range for a given quantity, or comment
not fitting the given quantity; or when no author was given in the comment.
Also, for some of the entries bearing as lab-code the country code, theoriginal reference had to be checked to possibly find the correct lab
code if this could not be guessed from authors' names and ZAQ.
A great effort was devoted to the proper blocking of unblocked area 3
entries, although the majority of area 3 entries was systematically blocked
since many years simultaneously with data compilation and EXFOR indexing
in Cinda.
'No book' flags have been attributed to superseded entries, abstracts
and progress reports, and less important reports when the same information
was available from a well known journal or report.
The old second line 'Z' entries have been replaced for area 3 andarea 4 entries.
Concerning area-4 entries, NDS had received from CJD two quite voluminous batches of corrections, by which the labcode 'CCP' could be replaced by the correct labcode. Unfortunately, these replacements were
far from being complete. NDS performed a lot of additional changes, again
based on comparisons of ZAQ-author-lab. At the same time, the blocking
within lab 'CCP' and with the corrected entries was done.
EXFOR
At this meeting we can celebrate the tenth anniversary of the Exforsystem. Following a series of programmers' workshops, the prototype ofManual and Dictionaries for the "Centre-to-Centre Transmission Format"
were formulated by P.M. Attree in October 19-69 with essential contributions by D. Cullen, M. Goldberg and others. Essential features of
the then existing neutron data systems SCISRS, NEUDADA and DASTAR
were incorporated into a common system, which was approved in November
1969 at the Fifth "Four-Centres Meeting" in Moscow and given the name
"EXFOR".
Although the system got meanwhile a number of revisions and refinements (in particular in the coding of the data definition under the keyword- 60 -

- 3-

NDS

REACTION), its principles are still the same.
To our knowledge it can be said that EXPOR is the first, and still
today the only functioning truly international exchange system fornumerical data (as distinct from bibliographic data). In these ten years
the Exfor files exchanged have grown to about 44 000 data sets (Exforsubentries) with 2.5 million numerical data records. In the field of
neutron data we have reached a respectable degree of completeness andreliability although a few gaps are still known. For charged-particle
and photo—nuclear data, the importance of Exfor is fast increasing, and
it is hoped that additional data centers will join the cooperation.
We believe that the definitions of the Exfor system have reached a
final stage, and that the system as it is, functions most satisfactorily.
But even a well running machine needs some servicing from time to time,
and that is what we shall have to do when discussing a lot of little
Exfor details during this meeting.

x f or compilation at NDS (KO)Recently we celebrated the 500th Exfor entry made at NDS. Meanwhile
we have compiled
550 entries, containing
4000

subentries, containing

55000 numerical data records
The compilation of new neutron data in Exfor continued (K. Okamoto,
N. Day Day, G. Lammer, 0. Schwerer), and also some gaps could be filled bycompiling older entries. Some gaps are still known to exist for India
and Pakistan. Again, contacts with the authors were taken importantresulting in a number of corrections and supplements to published data.
Several authors acknowledged the critical review of their data by NDS
during the compilation.
Transmission tapes were sent to the other centers in regular intervals.
In addition to neutron data, the following data types were compiled
in a non-systematic way, and only if the data were considered of top importance s-

Exfor V-series: evaluated neutron nuclear data that are notavailable in ENDP/B, UKNDL or KEDAK format. (According
to the request statistics, these data were requested andsent out frequently.)-

Exfor D-series: charged—particle nuclear data, integral anddifferential, when considered important as neutron source
reactions.

-trial entries were made to compile some experimental, evaluatedor recommended half-lives, when these are basic to theinterpretation of important neutron data experiments.

Notes:
1.

A "data set" is usually defined as an "Exfor subentry" containing for one nucleus a certain cross section
type as a function of energy resulting from one experiment. The size of a data set varies between one data
point and several thousand data records. For certain data types, in particular double differential data,
resonance—parameters, etc, the definition of a "data set" is varying, as different arrangements in Exforare possible.

2.

The statistics exclude superseded data sets. Data once compiled and transmitted, are often subsequently
revised by the author. The data are then retransmitted, whereby the superseded data are erased at all
centers automatically.

NDS

Exfor Dictionaries (OS)Dictionary transmissions have teen continued in a regular 3-months
rhythm. Since the last Nuclear Reaction Data Centers' Meeting in June 78
4 dictionary transmission tapes (9033 through 9036) have been sent out.
On an average 3 dictionary updates have been made between any 2 transmi ssions. The nuclide-dictionary 27 has been included into the regulardictionary transmissions.
The dictionaries 27 (nuclides) and 36 (coding of data definitions
under the keyword REACTION) have a special role as they do not contain,
like the other dictionaries, all permitted codes, but rather a collectionof code-combinations that exist in the file. Consequently, these two
dictionaries are being updated most frequently.
A number of dictionary updates had to be held back for many months,
as the explanation given together with the codes proposed was sometimes
insufficient and the response to our inquiries was sometimes very slow.
8.

Corrections of incoming Exfor TRANS tapes (OS)All incoming TRANS tapes are checked by the NDS check program which
produced a list of error messages. Using this report the important errors(i.e. errors disturbing our indexing or other programs or leading towrong interpretations of the data given) are corrected at NDS, wherever
possible, before merging the TRANS tape into the NDS Exfor master file.
When important errors cannot be corrected at NDS (because of missing
information or because restructuring of an entire subentry is required)
we request retransmissions from the originating centre. An extract of
the list of error messages with explanatory comments on corrections to
be made is sent to the originating centre. A compilation of frequently
occurring errors in REACTION coding and the structure of entries (which
partly lead to time-consuming correction procedures) was given in Memo
4C-3/233 of 1979-04-12.

Exfor Manual

According to an action from the last Data Centers Meeting we assisted in updating the NNDC Exfor Manual, however only with partial success.
We cannot regard the maintenance of the NNDC Manual as sufficienityspeedy
and reliable as required by our compilers and programmers. We therefore
cannot regard it as the official Exfor Manual as it is supposed to be.
Consequently it was decided that the updating of the NDS Exfor Manual willcontinue. Large parts of both Manuals are identical. However, essential
details seem to be more up-to-date and more practical in the NDS Manual.

10.

Documentation and customer services

In September 1979 the first issue of our "Nuclear Data Newsletter"appeared in order to intensify the contacts to data users in our service
area. This has the functions to advertise the services and functions of
NDS in general and to publicize news about Cinda, Exfor, evaluated data,
documents, meetings etc.

- 63 -

- 6-This newsletter, which must "be kept "brief but has a very wide distribution, is supplemented by a documentation series called "IAEA Nuclear
Data Services" with the report code "IAEA-NDS-... ". An index to thepresent status of this series is attached. The series will contain, foreach data library, a document summarizing contents, format and documentation as needed by a customer when receiving from NDS a data retrieval.
These documents will be small and distributed as Xerox copies, so thatthey can be updated easily whenever some news about a library comes toour attention.
This flexible system of the widely distributed Newsletter plus the
documentation series will replace our previous CINDU catalogue which wasa useful document but too tedious to update.
The first issues of the documentation series contain a thoroughdocumentation of the Exfor system and programs as operated at NDS.
11.

Request Statistics

The Request Log system and the Data Dissemination Log have been redesigned on a different basis. The system has been re-programmed, but
not yet all parts of it are in full operation. Dae to this transition,
the statistics do not exactly correspond to the tables presented in earlier years.
A "request" still corresponds normally to an "incoming letter",which however may contain "subrequests" if different categories, e.g.
'•evaluated data" and "documents" are wanted. This is about the same aspreviously. Hdwever, more often than so far, a request will be definedas "standing request".
This means: if a customer asks for data of a
specific reaction, he will receive immediately a retrieval of the datathat are on hand. But in addition, his request profile will be kept in
the system as a "standing request" for a reasonable period. During thisperiod his request profile will be compared with incoming new data, sothat he will be kept up-to-date in the field of his interest.
In 1978 the total number of requests received was about
more than in 1911, and that more or less for all of the five request
categories: evaluated data, experimental data, documents, bibliographies(in particular CINDA retrievals), computer codes related to theevaluated data files. In 1979 "the figures were somewhat lower for
the first half of the year; but for the rest of the year significantly
more requests are expected, due to our intensified contacts topotential customers by means of the new "Nuclear Data Newsletter",and due to the increasing collections of evaluated data, in particularwith the release of the total of ENDF/B-4 and parts of ENDF/B-5.
See the detailed statistics in the attachment.

WRENDA (D.W.M.)

WRENDA 79/80, to be issued in November 1979, will reflect numerous
recent changes to the WRENDA master-file of requests. It is the firstmajor file update since the production of WRENDA 76/77. To summarize
the changes (now complete), 465 requests listed in WRENDA 76/77 werewithdrawn, 487 were modified and 573 new requests were added, bringing
the total number of current requests to 1780, a net increase of 108.
The number of fission reactor related requests remains about thesame as before, but the number of fusion requests increased from 328 to449. As recommended at the 9th INDC meeting in May 1977, requests for
all applications will be combined into a single, unified list in the
WRENDA report. Because of this reorganisation of the list, most of thedescriptive material in the report has been rewritten.
Other changes to the list include a reduction in the amount of space
devoted to status comments. The only status comments listed in WRENDA
79/80 will be short comments, provided by the NDS, to indicate whichdata are under review by technical subcommittees of the INDC and NEANDC.
A third aspect worth noting is <%n increase in the number of requests
for high-energy neutron data, typically up to 50 MeV. Some of these
new high-energy requests specify reactions previously not allowed by the
WRENDA system, a fact which accounts for most of the 12 new reaction types
recently added to the WRENDA "quantities" table.
The issue of WRENDA 81/82 is planned for the summer of 1981. Thus,
the data centers should be receiving "country retrievals" to begin thenext WRENDA update cycle in August 1980. NDS plans to issue an updated
set of WRENDA input instructions at about the same time.

13.

The Data Index System

We were always convinced at NDS that data retrievals are mademost economically through a Data Index file extracted from the actual
data files, both connected by the accession-numbers only.
We have now a Data Index System in operation which indexes all
our data files: Exfor data automatically, non-Bxfor data by hand.
Eventually, the indexing of ENDP/B formatted data will be programmed.
The information stored in the index system includes Accession No.,
Reaction, Institute, Reference, No. of data points, Status, Author, andother items. Selective retrievals on all of these parameters can bemade, including each individual subfield of the REACTION string.
Each incoming Exfor TRANS tape is routinely indexed when being
merged into the Exfor master file. The evaluated data libraries kept
at NDS are only gradually being included in the index system.
Evaluated data are indexed by converting reaction-type numbers
to Exfor REACTION codes. But complete evaluations of neutron-induced
reactions may be indexed by means of artificial Exfor-type REACTION
codes such as (N,ALL), as usually no more detailed retrievals occur inthese cases. More detailed indexing can be done later as soon as actual
data requests demonstrate the need for further detail.

- 65 -

14*

Programming
Daring the past year the computer programming concentrated on-

improvements in the EXFOR check program; all centers
are familiar with the output as a feedback to their
TRANS tapes,-

reorganizing the Request Log system described above,-

the Data Index System described above.

In addition to the actual programming, systematic documentationof i t was completed to prepare for the change of programming staff.
See the l i s t of IAEA-NDS-documents.

At the new building, NIB will keep the presently existing Remote
Job Entry station. We will have in addition three Visual Display
Units (VIU) plus a hard-copy printer. I n i t i a l l y these will be
used primarily-

for accessing the Index;-

for correcting Exfor entries and other data f i l e s ;-for maintaining the data Request Log;-

for maintaining the address file and distribution
profiles;-for the input to the "International Bulletin on
Atomic and Molecular Data for Fusion".

Already now a l l these VHJ processes are in operation*lb.

INFORMATION SHEET

1»Introduction

In view of the considerable improvement in the accuracy and consistency of the properties of neutron sources relevant to neutron
metrology achieved in recent years, the International Nuclear Data
Committee at its recent meetings recommended that a meeting on Neutron
Source Properties be held in 1980. In response to this recommendation,
the IAEA Nuclear Data Section, with the support of the Hungarian authorities, in co-operation with the Institute of Experimental Physics ofthe Kossuth Lajos University acting as the host, plans to hold a Consultants* Meeting on "Neutron Source Properties'1 during the week 17-21
March 1980 in Debrecen, Hungary.

2.

Objectives

In addition to high-lighting current important developments in thisfield, the meeting will have the following specific objectives:

3.

-

To review the requirements and status of all properties anddata on neutron sources such as mono-energetic neutron-producing
reactions, white source neutron spectra, spontaneous fission
neutron spectra, gamma-neutron and alpha-neutron sources, filtered neutron beams and thermal and epi-thermal pile neutron
beams* The neutron energies to be covered extend from thermal
to 40 MeV and above. Plasma neutron sources are not to be
included,-

to identify the uncertainties in the properties of neutron
sources and the corrections needed to improve the accuracy
and consistency of neutron measurements, and-to formulate specific technical recommendations for future
work and its coordination.

Organization

To meet these objectives, the meeting will be organized aroundseven review topics, listed in the attached programme. The review
papers are to be comprehensive and concise surveys focussing on recent
developments. Reviewers have been requested tc include proposals for
specific recommendations for needed future work, which could be discussed- 79 -

further at the meeting and form part of the final conclusions andrecommendations. In addition to the review papers, it is expectedthat several papers, primarily on recent experimental developments,
will be contributed.
Following the presentation and discussion of the review andcontributed papers during the first part of the meeting, detailed
discussions will be conducted in plenary and by working groups.
Working groups will be responsible to formulate a final concise report on the present status and requirements concerning neutron source
properties and data, and to issue a set of conclusions and recommendations for the measurement or evaluation of specific properties anddata, with an indication of priorities and required accuracies.
Contributed papers
Contributed papers on any of the topics listed in the programmeshould be sent to the Scientific Secretary (Dr. K. Okamoto, Nuclear
Data Section, IAEA (new address: Vienna International Centre, P.O.
Box 100, A-1400 Vienna)) so as to be received at the.IAEA not later
than 31 January 1980.
Working Language; English, no interpretation will be available.
Publication of Proceedings
Subject of the approval of the Agency's Publication Committee,
the proceedings of this meeting, including the review papers, theworking group reports, and the conclusions and recommendations areplanned to be published.

4*

Participation

It is expected that the meeting will bring together about 25—30
specialists. In addition to the seven reviewers invited to attend
this meeting, other experts wishing to participate in this meetingat their own cost and to present a contributed paper, should informthe Scientific Secretary not later than 15 December 1979«- 80 -

ProgressJtejsovt for the NEA DATA BANK
(T-iken from the document SEN./DATA(79) 5 dated 17 Sept. 1979 of theOECD-NEA S t e e r i n g Committee for Nuclear Energy)

The present report is written in mid-September, someseven weeks before the date fixed for the return of the IBM
370/125 computer, and the formal end of the "conversion period"in which all the functions taken over from CCDK and GPL haveto be adapted to the new computing environment of the Data Bankc
Q?he major programming job has been the construction of an
integrated CIHDA/EXFOR data base on the PDP. 11/70 satellite
computer, conversion of data for loading on this data base, andwriting appropriate output programs» In. contrast, all the software brought from CPL for the computer program service work was
written for an IBM 370/^65 computer} and could be relatively
simply installed on the large OISI machines. It is for thisreason that rather more space is devoted in this report to development work for nuclear data handling, since this was the work
which had. to be finished within the conversion period. It will
be seen, that the combination of new software and a reorganisationof working methods has allowed an important gain in efficiency
on the data side : it is hoped that reprogramming and perhaps
associated gains in productivity on the computer program sideof the Data Bank can be achieved in 1980c
Although the possibility still exists of hidden errors in
the new software, and there has been a certain amount of trouble
with the PDP 11/70 hardware, both of which may cause delays, it
is possible to be confident that the conversion will be completed
by the end of October, and that the 370/125 computer may safely
be s-ent away at that time.

SEN/DATA(79)5~2

I. COHPUTEI* PROGRAM SERVICES
Routine Program Testing and Customer Services.
The output of computer programs tested and packages sentout to customers has, during 1979> been running steadily and at
approximately the same level as 1978. 730 requests were answeredin the first eight months of 1979 (610 complete packages, therest for documentation only), with material of U*S. and non~U,,S0
origin requested in proportions very similar to 1978 of 60°/o/h-0%.
So far, 70 programs have been tested (corresponding to an annual
rate just over 100 programs/year).
The queue of requests needing an answer currently stands at
194-, referring to 126 programs. 80 of these requests are for 54programs which have not yet reached the Data Bank, while out of
the 72 programs remaining, some 24- are at various stages of testing and packaging, and 4-8 are awaiting test. All these figuresfluctuate with time, but one which is unusual is that for programs
requested but not yet available to the Data Bank v This is attributed to delays in sending in programs, perhaps due to the rather
limited number of laboratory visits undertaken during the conversion, rather than to any refusal to put the programs at our
disposal. The fairly long queue of programs awaiting test should
be reduced in 1980.
;• .
Program testing work was transferred very smoothly during
1978 to the large computers of the CISI Saclay installation,
along with the master file maintenance and administrative programs which have run satisfactorily but rather expensively onthese disproportionately powerful computers. The 360/91, used
for much testing work because of its very reasonable charges
for CPU activity, is being replaced in September by an IBM 3033°
We have been assured that this change will not result in increased
Job execution costs.
Restrictions on Computer Program Availability
At the request of the Data Bank Committee, the Secretariat
has prepared a statement for submission to the Steering Committee
for Nuclear Energy recommending a more liberal approach in Member
countries to program sharing through the Data Bank. The draft
statement and a covering note by the Secretariat are included
as Appendix 1 O document No* NE(79)2^7». The problems in program availability do not appear in thestatistics given above, since users and indeed the Data Bank are
not usually informed about programs unavailable for exchange.
The publicity given by the Data Bank to new programs in its
abstracts publications is limited to programs already in the
Data Bank's collection, or which have been offered to it. The
problem of availability centres on the strictness with which thevarious definitions of "commercial value" are applied to programson the fringe of industrial applications, and more recently on atendency to reserve the updated versions of some major programsfor bilateral exchange rather than distribution through thesoftware centres.

Internal Development ProKr.amin.inty for Computer Program
Services
During the "conversion period" proper, only the mostbasic functions for handling the Data Bank's.distribution oftested programs are being transferred from the large IBM computer:to the PDP 11/70. The programs for retrieving from the compressor
file, and for tape copying work (which has required a generalised
tape copying routine to be written for the PDP 11/70, to supplement the very limited tape handling capacities of the standard
DEC software) are being re-written for the 11/70. It had proved
somewhat inconvenient to run these jobs, which required both
frequent tape changes and the use of unlabelled tapes, at the
CISI installation.
In 1980 the preparation of program abstracts, and theregular administrative information needed to follow the progressof program testing and requests, will be reprogrammed for the
11/70p Both these jobs are well suited to the direct on-line
preparation of input material, and will be included in a second"minor" data base, separate from the major neutron data base forreasons of security against programming and operator errors.
SECU and Publicity of non-U.S. Programs
A third SECU bulletin (Service on Experience in Code
Utilisation) has been issued, containing some 15 contributions
relating to the earlier SECU study on Shielding and Cross-Section
Calculation Programs°
A seminar is to be held at the National Energy Software
Centre, ANL, to publicise some non-US program packages expected
to be of interest in the U.S., but little known there. The
pressure of work at the end of the conversion period has madeit preferable to postpone the seminar until early 1980.
The regular information appearing in "Hews from the Data
Bank", about the current program collection and new additions
to it, will be supplemented by an update of the European program
abstracts, now in preparation.
II. HIJCLEAR DATA ACTIVITIES. • , The nuclear data work of the Data Bank has been very muchinfluenced by two deadlines: the publication of the archivaj.
edi^on_oX~CIMt!* and the need to prepare as much as possible of^ ® ejglier' data stored in HEUPADA format for exchange under
EXJFOR conventions before^the IBM 3^712^ computer was sent back*The work done in pfep~arTn^l:he "archival edition of CINDA has
naturally proved extremely valuable in recompiling these older
data, as well as in reducing the preparatory work needed for
new data compilations.

-85 -SEN/DATA(79)5

Data Compilation in CINDA and EXffOR
1979 saw the end of a concentrated effort by all four
neutron data centres to improve the consistency and quality of
the CINDA index to neutron data publications. An archival publication of the complete file was prepared at the Data Bank in
April 1979 and has been printed in three volumes (two volumes
up to 1976, and one supplement 1977-1979) by IAEA. A first
update of this supplement will be made in October 1979*
The PDP 11/70 computer with its multiuser timesharing .
operating system arid file editing facilities has allowed""""! newapproach to compilation"of experimental' neutron data into the
EXFOR format. An interactive,data compilation program wasinstalled and testecTHuring the Spring of 1979, andTTias much
improved the speed with which data ecu be compiled in KXITOE. c.nd
reduced the number of errors to be eliminated before an exchange
tape can be transmitted to the other data centres and merged in
our own data base.
Including recompilations from the older 1T3UDADA file, which
could be partially automated by computer transposition of theexisting data tables, supplemented by descriptions newly added to
EXPOS, standards, cjDnrojjLa£ij2n_j^s_j^
rate ofapproximatel_y_JJ-QO__EKgOR works/year <, Where the compiTaTfion effort
i^"~d'irec:fc~ea."en-Eirly to new compilations, a rate of perhaps 250
compilations/year may be achieved, which is slightly in excessof the increased rate at which new experimental work Is now being
published.
Conversion of the NEUDADA file was begun with those data
sets containing larger data tables, where computer transpositionof these tables to EXFOR would save labouro So far, at the Data
Banl.?:, all HEUDADA data sets containing more than 20 data points
have been recompiled, and the smaller data sets are being listed
for manual transfer to the PDP 11/70 after the return of the IBMcomputer„ Some 15,000 data points remain to be reviewed, and wehope to finish this work early in 1930.
,.
A similar effort has recently been finished by HNDC andNDC/IAEA in conversion of the old SC1SRS file, so that we can
expect that by early 1980 each of the four neutron nuclear data
centres will have, for the first time, identical experiental data
files. This is obviously of great importance for the consistencyof nuclear data evaluations in all countries.
.Requests for nuclear data from the Data Bank are currently
running at about 40 per month, split evenly between experimental
and evaluated nuclear data. The number of requests has shown asteady increase over the last five years, articularly for evaluated data. A catalogue of data files available from-the Data
Bank has recently freen prepared, end published in NNDEN/25.
Copies of the current list, including several new files acquiredin"1979 and some selected files from EHDF/B V, can be obtained
from the Data Bank on request.

Customer Service on Nuclear Data
The change in the' data storage system for experimental data
has produced some changes in the way data is presented to physicists. Experimental

centres". ~¥hile this development is a very natural one from thepoint of view of more efficient data handling and file maintenance (one physicist was employed nearly full-time on NEUDADA,
in addition to the work carried out in EXFOH), the need remains
for a. fixed fjleld "li^~bj^MneJl__forja.at for sorting, merging andgraph!c~al~~dispTay of data sets for which treatment is required.
A llcomputatipSaLll__fQ.Emai., similar in conception to that of
HEUDADA," "but with some improvements "better to accommodate double
differential cross-sections, has been developed and is describedin NNDEN/26. An interim user guide for numerical data has been
prepared, very similar to this description but including dictionaries of reaction type codes, e t c , and can be obtained onrequest from the Data Bank. Users of NEUDADA should find that
only minor modifications to their programs are necessary inorder to accept data in the new format„
One application of this new format is an adaptation for
the PDF 11/70 of programs written by Prof. Vonach1s group for"best fit" evaluation of threshold cross-sections, including
covariance information, and using data retrieved directly fromthe integrated data base. Documentation on these Fortran programs can be obtained on request, and they may be used by visitors to the Data Bank. Alternatively, copies of the source
programs can be supplied for implementation elsewhere.

Conversion Work for Data Handling
While programming work has been slowed down by software
problems with the DBI1S-11 data management system, and some hardware faults on the PDP 11/70, a full CINDA/E3GP0S data base has
been loaded (in early September 1979)- As is explained elsewhere,
several man-months work remain to transfer some computer programservice work to the 11/70, while the important effort of documentation and establishment of good working procedures in ourtimesharing environment can be neglected only at the price ofrevei'Gion to chaos xvithin a few years. Most of this "tidyingup" will be carried out in 1980.
Computer program development is under way for storage andselective retrieval from all the major evaluated data files.
Pietrievals will be available in original format tapes, edited
listings and eventually in the same computational (plotting)format- adojyued for the experimental neutron cross section data.

Neutron Data .Publications
Besides its work on the archival edition of CINDA, theData Bank has participated in the preparation of a new editionof the World Requests for Experimental Nuclear Data (WRENDA)
which is currently being printed "by IAEA. New requests andmodifications to existing requests from NEA Member countries
were coded at the Data Bank for the updating of the Master Fileheld at NDS/IABA. The scope of this edition is somewhat wider
than that, covered by the NEACRP/NEANDC "highest priority" list,
but all these requests, have been entered in WRENDA.
A minor innovation has been the inclusion of some information about the Data Bank services in"NNDEN/25 and 26. Aseffort becomes available to develop the necessary index extraction programs operating on the data base, more neutron data
information may be included in "News from the Data Bank"- 88 -

October 8-12, 1979

I.

GeneralThree new staff members have been added since our last report to theReaction Data Centers Network. Our two programmers, Jean Burt and John
Guthy have left and been replaced by Don Swinford and Paul Dempsey. The
open EXFOR compiler position was filled by Mike Fanelli. The DEC-1091
computer and peripherals described in our last report, was installed in
March 1979 and is performing up to expectations. Program conversion
problems were minor.

II.

WRENDAThe biennial review and updating of the United States Nuclear Data
Request List was completed in January 1979. A complete set of U.S.
entries in WRENDA format was submitted to NDS at that time.

III.

CINDA
In January 1979, NNDC completed its review and correction of Area 1
entries. Corrections were sent to NEADB in time for the archival CINDA
publication. All old data translated from SCISRS-I to EXFOR was indexed
during this review. Extensive contributions to this effort were made by
the personnel in the Physics and Support Groups.
The normal CINDA compilation activity has continued. Three special
indices were prepared for the NEANDC Meeting on Data of Higher Pu and Am
Isotopes, the Third International Symposium on Neutron Capture Gamma Ray
Spectroscopy and the 1979 DOE-NDC Status Reports.
In the coming year we intend to index ENDL and those parts of ENDF/B
which have been released for general distribution and expect to prepare
indices for the Knoxville conference and the 1980 DOE-NDC Status reports.
With the completion of the 1979 CINDA Supplement, NNDC will assume
full responsibility for the Area 1 entries in the CINDA master file.
Updates to these entries will be transmitted at regular intervals to
NEADB in the agreed exchange format. NNDC will continue to receive updates for areas 2, 3, and 4 from NEADB but now in the new exchange format.
NNDC is now prepared to offer back-up to NEADB on both file maintenanceand book tape generations. More details on our system are given in our
separate DBMS Systems report.

IV.

EXFOR
In the period June 1978 through September 1979, 16 transmission tapes(TRANS 1087-1102) have been sent out containing 226 new entries and numerous corrected entries. 152 post-1970 data sets have been compiled.
A check of EXFOR versus CINDA has been done in connection with the
CINDA cleanup and a list of Area 1 data not in EXFOR has been produced.
The references are being checked and missing data compiled on a time
available basis.

Evaluated Data Neutron Data
The General Purpose File for ENDF/B has been released. ENDF/B-V
data files for cross-section standards, dosimetry and actinides areavailable for unrestricted distribution. The fission product filewhich will also have general availability is expected to be ready forrelease by the end of 1979. All materials have passed extensive computer checking and review by experienced evaluators. The files are
now being tested against benchmark experiments.
Work is in progress toward defining a more general ENDF format tohandle non-neutron projectile as well as other additional reaction properties. Further tests on the format are in progress to test its practicability.

CPND Bibliography
the bibliography is continuing to grow at an accelerated rate. Asof the last week of September, 1979, it had increased in size approximately
30% over the size as of January 31, 1979.
The 1979 edition of BNL-NCS-50640 has been published and distributed.
There were no changes in format over the 1978 edition. The rapid growth in
the size of this publication will probably mean some major format or publication changes in future editons.
A tape of the current contents of the file has been distributed on aperiodic basis to KACHAPAG, CAJaD, CJD, NDS-, LRL along with the latest
format manuals.
A DBMS system is being designed for the bibliography and should be
operational by January, 1980.
McGowan-Milner Data File
The index to this file should be completed by the end of 1979 (e.g.
brought up to CPND bibliography standards).
The many requests for data from the CPX data file has required thedevelopment of a set of simple Fortran programs which use the contents of
the index to retrieve specific data sets from the data file.
Data of interest to our CPND evaluation activities will be translated
into EXFOR.
Howerton Data File
Since this file is fairly limited in scope (i.e. scattering data fortarget and incident A<4), the entire file is sent to satisfy any requests
for data contained in it.
Experimental CPND Compilation
The first TKANS tape of CPND compiled at the NNDC containing experimental data on the (d,n) and related reactions was sent to KACHAPAG in thelast week of September. Since CAJaD and NDS are also actively compiling
CPND, copies of the tape were sent to these two centers.

Charged Particle Nuclear Data (cont)Work is in progress to collect experimental data on nuclear reactionsof interest to nuclear medicine. The evaluation of T (d,n) reactions was
discontinued because several other groups are already planning to evaluate
this reaction.

VII.

Photonuclear Reaction Data
The expected release of a new version of the Berman library has notoccurred. Therefore, the conversion and transmission in EXFOR was notcompleted as promise.

VIII.

Customer Services
The request statistics for the January 1, 1978 to December 1, 1978,
are attached.
A computation format for a vs. E cross sections data has been developed
and output is produced in either a table format or a self-contained line
format.
Improvements have been made on the computation format for resonanceparameters, based on experience over the past year.

IX.

Publications
The ENDF/B-V Formats and Procedures Manual (ENDF-102) and the ENDF/B-V
Summary Documentation (ENDF- 201) are now in press.
The fourth edition of BNL-325, Vol. 1 Resonance Parameters will be published in two parts. Part I, Z=60, and Part 2, Z=61-100. It is anticipatedthat the first part will be completed sometime this fall while the second
part in July of 1980. The recommended resonance parameters are based on experimental data stored in CSISRS library. A computer program retrieves thedata from the library, transforms it into a standard from (such as gr n values)
groups the data according to resonance energy and gr n ° values, then extracts aweighted and unweighted average with internal and external errors.
Some of the new features include the following:
1. An expanded introduction emphasing the systematics of average s- andp- wave radiative widths and neutrons strength functions.
2. Emphasis on average level spaclngs for s- and p-wave resonances. A
staircase plot is produced by the computer and a least square fit is made,from which an average level spacing is obtained. Inspection of this plot
enables the evaluator to determine the neutron energy EJJ beyond which levels
are being missed. Subsequently, a least square fit is produced in the energy
region E]_-En. In addition, a most probable value of the spacing D* is computedin this energy region.
3. New quantities which have not been included previously will be recommended. These include the y-ray strength functions for s- and p- wave
resonances; incoherent scattering cross sections, 30 keV Maxwellian average
capture cross sections, and the calculated capture and fission cross sections
from positive s-wave resonances with spins 1+1/2 and 1-1/2.

-96 -App. 9NNDC
IX.

Publications (cont)4. A visual indication of energy regions in which no measurements
were carried "out will be made.
5. The recommended resonance parameters are cast into an ENDF format.
Spins of resonances which have not yet determined are randomly assigned so
as to follow the (2J+1) level dinsity formula.

The ENDF computer codes(with minor changes) can then be used to operate on the recommended
resonance parameters to calculate (1) capture, scattering, and total crosssections, (2) absorption, capture, and fission resonance integrals, (3)average capture widths, etc.
6. Parameters of bound levels are determined in order to achieve
consistency between measured and calculated capture cross sections andcoherent scattering lengths.

Future Meetings
Symposium on Neutron Cross Sections from 10-50 MeV will be held at
BNL, May 12-14, 1980. The meeting will review progress since the last
symposium in May 1977, and will assess the current status of data andevaluationskh- 97 -

BROOKHAVENNATIONAL

LABORATORYMEMORANDUM
DATE:September 28, 1979

TO:

Reaction Data Center

FROM:

NNDC

SUBJECT: Fission Spectrum Data

A workshop on fission spectrum data, their analysis and evaluation washeld at the National Nuclear Data Center on October 23, 1978 with Leona Stewart(LASL) as Chairnan. As a result of the ensuing discussion, it was realized
that, fission spectrum data should be available at cross section data centers
for subsequent analysis applying multiple, scattering and other corrections.
Such corrected data could then be used to carry out an evaluation to arrive
at a set of best parameters for representing the spectrum. In this connection,
the difficulty of obtaining such data was mentioned and NKDC was charged by
the Chairman and members of the workshop to collect and maintain such data
in its files ir. cooperation with other data centers.

Reference
ENDP/BREFERENCE GUIDELINES FOR ENDF/B

Case I:Use of ENDF/B evaluations in a secondary manner, where many
elements are used together, or other cases where NO CONCLUSIONSARE DRAWN CONCERNING QUALITY OF EVALUATIONS. In this case
we propose the following form for ENDF/B-V.
"ENDF/B Summary Documentation, BNL-NCS-17541 (ENDF-201),
3rd Edition (ENDF/B-V), edited by R. Kinsey, available
from the National Nuclear Data Center, Brookhaven National
Laboratory, Upton, N.Y. (July 1979)."

Case II:

Use of ENDF/B evaluations in a direct manner, for example
comparing measured results with evaluated results, or ANY
CASE WHERE CONCLUSIONS ARE DRAWN ABOUT AN EVALUATION FOR A
PARTICULAR MATERIAL. We propose, for 1 2 C from ENDF/B-V as
an example:"ENDF/B data file for 1 2 C (MAT 1306,MOD 1 ) , evaluation by
C.Y. Fu and F.G. Perey (ORNL), BNL-NCS-17541 (ENDF-201),
3rd Edition (ENDF/B-V), edited by R. Kinsey, available
from the Brookhaven National Laboratory, Upton, N.Y.
(July 1979)."

Case III:Use of ENDF/B evaluations to generate a multigroup library.
In this case we propose that the report describing the library
contain a table which includes the following information foreach evaluation:
Material

MAT,MOD

Authors

Institution

This table may contain in addition other useful information
concerning the multigroup library. ' Finally, a generalreference should be given of the type described in Case I.

As shown in Cases II and III, a correct reference would contain the material
name, MAT number, author list and institution(s), along with a reference
to the Summary Documentation. In addition, for ENDF/B-Version V, updates
will be allowed to the evaluations prior to the release of ENDF/B-VI. Thus,
references to ENDF/B-V evaluations should also contain the appropriate MOD
number, which serves to define the current status of an evaluation. Allof this information is readily available in File 1 of each evaluation. The
only exception to the above cases would be where a published document, prepared by the authors of the evaluation, is available. This document should
then be referenced directly.

responsible for a defined service area.
The four centers and t h e i r2.

respective service areas are:a)

The National Nuclear Data Center (NNDC), at the
Brookhaven
National Laboratory (USA), services the USA and Canada.

b)

NEA-Data Bank (NEA-DB) , at Saclay(France),
non-American member Countries o f the OECD.

servicesthe(USSR)

Four-Center Commitmenta)Within the scope of this protocol each center is expected
to compile the data measured in its service area as fast
and as thoroughly as possible.

b)

The four centers agree that "new" data should be coded in
EXFOR(where new is definedas data collected by thecenters at the time of, or after, formal transmission ofdata
was initiated).
This
does not preclude thetransformation of "old" data into EXFOR.

c)

Each center may compile data measured outside its service
area.
Regular transmission of EXFOR data from any one
center shall include data only from its own service area.

d)Each center shall keep an archival copy of the latest
version of each of the EXFOR entries which it originatedand shall be ready to provide the data to any center should
it be required.

CORRECTIONS, REVISIONS AND DELETIONS OF TRANSMITTED EXFOR ENTRIES

1.

Corrections or revisions
In the event of partial corrections or revisions of an EXFOR
entry, at least the subentry containing the correction shall betransmitted by the originating center to the other centers, inaccordance with the conventions laid down in the EXFOR Manual.

2.

Accession numbers used
Once transmitted, no accession or subaccession number should bereused for another entry or subentry. The accession number ofa deleted entry (subentry) should not be used for another entry(subentry).

Updating o£ Dictionariesa)

To prevent duplications and conflicts,
the
NDS
is
responsible for the coordination and the updating of the
EXFOR dictionaries.

b)

Alterations (meaning additions, corrections or deletions)to EXFOR dictionaries can be termed consequential, which
would entail changes in transmitted data, and thus required
NRDC approval, or inconsequential, which would not entailchanges in transmitted data or NRDC approval.
Without
exception, all changes to Dictionaries 1, 2, 4, 10, 11, 12,
16, 2M, 28, 29, 30, 31, 32, 33, 31* and 35 are consequential
and require NRDC approval.

c)Consequential Dictionary Alterations
Alterations of EXFOR dictionary entries which
entailchanges to data already transmitted cannot be implemented
without specific NRDC approval.

d)Inconsequential Dictionary Alterations
Proposals for alterations of EXFOR dictionary entries which
do not entail changes to data already transmitted, andwhich do not fall in the Dictionary list given in F.1.b.,above, should be submitted by the centers to NDS, together
with their mnemonic terms and definitions, via CP Memo.
NDS shall transmit the approved dictionary entries to all
centers simultaneously, in the form of photocopies of the
input forms used for the NDS dictionary update program.

e)2.

In their function to update EXFOR dictionaries, the NDS isgiven some latitude in reformulating the definition, butmust not chang,e the meaning without the approval of theoriginating
center.
In questionable cases NDS shallconsult with the other centers for their opinions.
It isthe responsibility of each Center to update its own sets ofDictionaries.

Routine Transmission of Dictionaries
The NDS will transmit a complete set of dictionaries to theothercenters
every three months, as a separate EXFOR
transmission.
