Abstract
This report summarizes the 1983 coordination meeting of the nationaland regional nuclear reaction data centers, convened by the IAEA at
regular intervals. The main topics are
the international exchange of nuclear reaction data by means ofthe "EXFOR" system,
the futher development of this system,
the sharing
compilation,of the workload

forspeedyandreliabledata

the exchange of specialized and evaluated data libraries,
the role of ENDF/B as an international format for the exchangeof evaluated data,with the goal of rendering data center services to data users in IAEA
Member States by means of computer retrievals and printed materials.

The actual discussions

Introduction
J.J. Schmidt opened the meeting. He requested a minute of silence
honouring the late Prof. L.N. Usachev and commemorated his merits forthe international co-operation in the field of nuclear data.
B. Kuzminov welcomed the participants on behalf of the
Fiziko-Energeticheskij
Institutewhichcelebrated
the
30th
anniversary of nuclear power in the USSR. He stressed the continuing
importance of the nuclear data programme of the IAEA noticing still
increasing requirements for more precise nuclear data not only in thefield of nuclear energy but more and more also in non-energy
applications.
V.N. Manokhin expressed the pleasure of the Centr po Jadernym Dannym
for having the opportunity to host the meeting together with the twocenters in Moscow. He introduced the meeting participants.
J.J. Schmidt was elected as chairman.

I. Kondurov, Gatchina, gave a brief report on his NSDD activities,
they finished the A=134 mass chain evaluation, A=133 and 180 are in
progress. They contribute to and distribute ENSDF information. They
are working on a special file for nuclear activation analysis.
CAJaD (see SR5) extended the compilation work to CPND from various
countries. This was highly appreciated by the participants.

- 14 N. Tubbs (see SR2) emphasized the extended co-operation of the NEA-DB
with non-OECD countries by extension of the evaluation newsletter
NNDEN and by increased services of the Computer Program Library(CPL). He requested that there should be more input from non-OECD
countries to the CPL.
In connection with the N0£ report (SR3), it was requested
disseminate regularly early information on IAEA Meetings.

2.2 The meeting reviewed the actions and recommendations from theprevious meeting, see INDC(NDS)-141. Some continuing actions were
included in the new list of actions starting on page 23 of thisdocument.
2.3 J.J. Schmidt reviewed some actions and recommendations resulting fromtffie Hth" TRDC Meeting. In particular he announced the Agency's
Advisory Group Meeting on Nuclear Standard Reference Data to be heldin Gee!, Belgium, in November 1984.

3. Policy discussions
Part of this agenda item was dealt with in a Discussion of Center
Heads.
The main topics of the center heads' discussions concerned- completeness and correctness of CINDA in order to publish in
spring 1984 a high quality archival issue CINDA-B, requiring inparticular an intensified workplan at CJD,
- speed and completeness of the EXFOR data transmission where somesignificant delays had been encountered,- importance to improve the exchange and speedy release of evaluateddata and of related computer codes.
For resulting actions and recommendations see page 23 and following
pages. Additional parts of this agenda item were discussed inplenary, as follows.
3.4 Priorities of CPND and PhND compilationa) CPND
J.J. Schmidt reported on an action requested by the INDC (see WP3item 4) to analyze the user needs for compilations of CPND. This
information is required by the INDC in order to estimate the impact
to data users caused by the closing down of KaChaPaG and as justification to stimulate more CPND compilation.

- 15 The meeting considered the data needs for CPND and Photonuclear data
as listed in INDC(NDS)-141 pages 75-77 (see WP14). All participants(except NEA-DB having no mandate for CPND) were asked to report to
J.J. Schmidt as soon as possible about-p r i o r i t i e s of data needs
completeness resp. incompleteness of existing data f i l e sestimate of resulting compilation workload required and whether
this can be done by the existing centers or not.

See action 7.3.

F. Chukreev replied that of the items listed in WP14
- CPND for radioisotope production- CPND for fusion, and- CPND for neutron production
are considered as most important. He expresses concern that CPND
compilation finds insufficient support in most countries, but that heis prepared to continue CPND compilation with widened scope as muchas possible with the staff available. This is much appreciated by
the meeting participants.
A. Hashizume reported that he is prepared to start Exfor compilation
at RIKEN of CPND for the production of about 20 radioisotopes that heconsiders as most important. In addition, data for unwanted parallel
RI production are needed to be compiled. After compilation ofexperimental data he plans data evaluation and to provide evaluated
CPND in Exfor format. In contrast to the Study Group covering also
differential data, RIKEN is interested in cross-sections andthick-target yields as function of projectile energy.
See actions 7.4 - 7.6.
F. Chukreev pointed out that there are some papers containing CPND
and NND which should be compiled together by the same Exforcompiler. CAJaD has sent to CJD a tape with some neutron E.xfor
entries compiled from such papers. Action 6.6. It was agreed thatfor the time being CPND and NND compiled from the same paper, should
not be transmitted in the same entry. Internally, of course, eachcenter is free to decide what to do in addition to the agreed Exfordata transmission.
H. Lemmel reported about NDS activities on CPND compilation. Efforts
to find a new CPND center in replacement of KaChaPaG had concentrated
on FRG and Japan. A group at Cologne, FRG, had shown much interest
but could not find financial support. More successful were thecontacts with Japan. The meeting highly welcomed the participationof the RIKEN group and the presence of Dr. Hashizume at this meeting.
A. Ignatjuk stresses the importance of having proton-resonance data
to be analyzed with NEA-DB computer codes used for neutron
resonances. N. Tubbs confirms, but he is not sure whether there areenough proton-resonance data and sufficiently reliable data,(action 7.7)

- 16 F. Chukreev said that, according to a continuing action from previous
meetings, (d.pf) and (t,df) data as required for neutron data
evaluation, are compiled by CJD and CAJaD in co-operation. He wasdisappointed that there is no compilation manpower for these type ofdata in the other service areas, although these data are consideredas important.
b.) PhND
See actions 8.1 - 8.8.
The 1979 Berman library could not be obtained by NNDC.
CDFE had no problems with the use of EXFOR for PhND. It was foundregrettable that CDFE is the only center so far to compile PhND in asystematic manner. The main interest of CDFE is photon activation
analysis, including photon activation cross-sections and spectra ofsecondary photons for identification of elements/isotopes. According
to the data requests received from USSR institutes and universities,
there is interest in data on ( Y , Y ' ) , (y,n), (r,p), ( Y , O ) .
3.5 CPND bibliography
C. Dunford says that NNDC presently reviews the possibility ofcontinuing the CPND Bibliography. It would be a supplement to theone discontinued Tn 1982 but produced in a different way: the"Nuclear Structure Reference" system has tags recently introduced bywhich retrievals for the bibliography of integral CPND are madepossible. The meeting participants confirm that the Bibliography ofintegral CPND is an essential basis for the EXFOR compilation andencourage NNDC to continue. (Action 7.8)
3.7 Date and place of next NRDC Meeting
Continuing NRDC Meetings in intervals of 18 months, the next meeting
would be in spring 1985 in Paris.
It was felt, however, that for the technical staff 18 months
intervals are too long, and a meeting in Sept. 1984 in Vienna would
be desirable. For center heads, who occasionally meet on otheroccasions, 2 year intervals may be sufficient.
See actions 1.12 - 1.14.
If the technical meeting is not possible, the old schedule should bemaintained.
3.8 USSR publications
F. Chukreev reports that he has distributed the proceedings of all
the All-Union Conferences since 1977. I. Kondurov is organizer of

- 17 these conferences. In view of the difficulties to obtain theseproceedings in the Western countries, NDS and NNDC should sendrequests for proceedings to I. Kondurov. (Action 1.2)
It was noted that in USSR publications often the institute of theauthors was missing, and CJD was asked to approach editors.
(Action 1.3)
3.9 Planned meetings
See actions 1.9 - 1.11.
The next international nuclear data conference w i l l be in Santa Fe,
USA, 13-17 May 1985. M.K. Mehta, NDS, w i l l be on the Advisory
Committee to take care about participation from non-OECD countries.

N. Tubbs announces- a NEANDC meeting on analysis codes for datatransmission data, at a date not yet fixed

reductionfrom- a NEACRP meeting on the treatment of the resonance region inreactor calculations, perhaps in Jan. 1984
- The NEANDC meeting in Tokyo, March 1984
- in 1985 a meeting on optical model codes, the emphasis being
influenced by JEF benchmarks.
F. Chukreev announces the annual nuclear spectroscopy conference inAlma Ata, April 1984.
V. Manokhin announces that the first volume of the 1983 Kiev
conferences will be published in Nov. 1983, the last volume in March
1984.

EXFOR Actions page 26
and WP6 page 73
4.3 Proton resonance data
The compilation in Exfor of proton resonance data had been
recommended by the IAEA Advisory Group Meeting on Basic and Applied
Problems of Nuclear Level Densities, BNL 11-15 April 1983 (seeBNL-NCS-51694 p.25), for the purpose of obtaining level-density
information required for neutron data evaluation. The 4 Centres had
been urged to compile these proton resonance parameters so that they
become accessible with similar ease and completeness as has beenachieved for neutron resonance parameters in recent years.

- 18 This recommendation
meeting, May 1983.

had been endorsed by the INDC at its

13th

The neutron data centers, though presently not compiling such data,
took note of this recommendation (see Exfor Conclusion no. 4.11).
The same level-densities meeting also requested compilation of (a,n)
and (p,n) data for heavy nuclei (A above 70) and (p,a) and U , p ) datafor higher nuclei, also energy and angular differential data of (p,n)
and (a,n) reactions (see BNL-NCS-51694 p. 28-31), for the purpose ofobtaining level-density information for neutron data evaluation.
5. Evaluated data
5.1 Status of ENDF/B formatted evaluations and related computer codes
V. Manokhin and A. Blokhin report on the progress on checking andcorrecting the Dresden silicon evaluation. CJD has implemented thecode FIZCON and is implementing at Minsk and Dresden. On iron there
is no newer version than that available at NDS. NDS should send to
CJD the most uptodate versions of the codes CHECKER, FIZCON, PSYCHE.
C. Dunford reports that NNDC, though working on a CDC computer, tests
the IBM version of the codes CHECKER, FIZCON, PSYCHE. They have aplotting code which could eventually be supplied for VERSATECH.
N. Tubbs reports on the JEF activities at the NEA Data Bank, see
status report SR2.
CJD has F0RTRAN4. F0RTRAN77, which is quite different, is notavailable, so that CJD must modify codes received in F0RTRAN77.
5.2 - 5.4 ENDF format
M. Nikolaev reported that the ENDF/B format was recognized as a good
format, and that the USSR changed over from SOKRATOR format to ENDF/B
format. Of the encountered d i f f i c u l t i e s many are pointed out in theformat documentation ENDF-102 but without conclusions how to solve
them. The main d i f f i c u l t y they had is the rule that the boundary
between the resolved and unresolved resonance region must be the samefor all 1-states.
They would prefer a formalism giving f i r s t thedata for 1=0, then for 1=1 etc, though there would be otherd i f f i c u l t i e s . As an interim solution they created a r t i f i c i a l datafor 1 = 1. They have also used, a r t i f i c i a l l y , three MAT numbers for
U-238 s-wave, U-238 p-wave, and U-238 d-wave as separate "isotopes"of same abundance.
C. Dunford replied that this problem is solved in the US byintroducing an a r t i f i c i a l background cross-section to account for the
missing p-wave part.

- 19 -

M. Nikoiaev reported that Konshin recommends to use Reich-Moore
parameters?" C. Dunford replies that the format exists in ENDF/B but
that, according to present procedure, this format should not be usedbecause of the lack of corresponding computer codes. Whenever such
codes become available, there w i l l be a new situation.
I t was concluded that, before introducing new format or procedures in
ENDF/B, an estimate is required, how much more accurate data
calculations would be. I f an improved accuracy is not demonstrated,evaluators should be asked to bring their evaluations as accurately
as possible into the agreed ENDF/B format.
D. Hermsdorf presented two papers on-

Recommendations for the use of formatting rules in ENDF format.
Remarks on data of nuclear reactions induced by fast neutrons andtheir representation in the format ENDF.

Based on his experiences with the silicon evaluation he noted inparticular:-

multiparticle reactions have insufficient possibilities for coding
in ENDF format
neutron-emission data cannot easily be coded in ENDF format
for angular distributions of fast neutrons, the rules of f i l e 6
should be re-activated to store energy-dependent Legendre
coefficientscharged-particles spectra from neutron-induced reactions are needed
the ENDF formats and procedures manual requires editorial
improvements

He requested an information system for news on the ENDF/B format andon related computer codes.
M. Nikolaev noted the following deficiencies:-

for U-238 more open channels are required in the unresolved energy
regionthere seem to be some problems with the condition that all partial
cross-sections must add up to the total cross-section throughout
a l l energies
the rules must be laid down for calculting the thermal
cross-sections from the resonance-parameters

N. Tubbs reported that not a l l options of the ENDF format are used
for JEF. In JEF parallel f i l e s are kept of pointwise data andresonance-parameter data.
F. Chukreev stated that i t would be useful to include in ENDF
charged-particle reaction data, in particular neutron-source data.
C. Dunford reported that the US Cross-Section Evaluation Working
Group (CSEWG) w i l l meet in May 1984 to decide upon ENDF format
modifications to be adopted for ENDF/B-6. Changes w i l l be adopted
not on theoretical needs but only on the basis of strong arguments.
Any change adopted has serious consequences in the ENDF computercodes.

- 20 M. Nikolaev agreed that the range of data to be included in ENDF/B
should not be too wide. Reactor calculations should remain the
primary purpose. ENDF/B is not really an exchange format but aformat for data input into computer codes.
The meeting supported the INDC recommendation to have a specialists'
meeting on the ENDF/B format. This meeting should be held in Vienna
in the first week of April. Proposals should be submitted as earlyas possible so that they can be reviewed in time before the meeting.
5.5 Other evaluated data
J.J. Schmidt reported that the ARAMAKO file was used in many
countries. NDS will send to CJD the ARAMAKO distribution list inorder to stimulate the release of a more recent version of it.
(Action 1.5)
6. Special matters on neutron data
6.1 - 6.4 CINDA
The improved format of the Supplement book (4C-3/266) was approved.
The schedule for the new archival issue CINDA-B (4C-3/259) was
confirmed. The cutoff date between CINDA-A and CINDA-B will be
optimized by NEA-DB.
On Cinda rules see CINDA conclusions and actions, pageFor area 4 Cinda matters see appendix, WP9.
6.5 WRENDA
WRENDA 83/84 is in print. Further issues will be published in cyclesof 4 years, according to an INDC recommendation (see report INDC-39).
6.6 - 6.9 Neutron data in EXFOR
See actions 6.1 - 6.11.
During the past year lack of manpower did not permit many
completeness checks. A survey made by NNDC, see appendix WP7,
indicated areas where completeness of compilation and speed of datatransmission still require improvements. Attention is drawn to thegraphical cross-section atlas for o(E) planned by NNDC, see action
6.1.
7. Topical Discussions
7.1 A. Ignatjuk: Level density models for nuclear data evaluations.

- 21 The Fermi-gas model being no longer sufficient, one must consider at
least three effects: Shell effects, superconductivity
effects,
collective effects.

Conclusions about CINDA

2.1

The quantity code POL is used for a l l polarization measurements onoutgoing particles following scattering or any other reaction.

2.2

The quantity codes NG and SNG are c l a r i f i e d such that NG is used
only for fh~e (n.r) total cross-section and the (n,y) partial
cross-sections
leading toa metastablestate.
All
otherquantities referring to the (n,y) reactions are coded under SNG.

2.3

The treatment of cross-section ratios is c l a r i f i e d as follows:Ifa ratio is relative to a quantity included in the EXFOR l i s t ofstandards, no CINDA entry is made for the standard. I f both (ornone) of the reactions of the ratio are standards, CINDA entries
are made for both reactions.

3.

Actions about CINDA

3.1

4. EXFOR conclusions
4.1

The country code of Japan is changed to JPN.
4C-2/119.

Compare Memo

4.2

"Vector COMMON" rules are confirmed to remain strict, inparticular the rule that headings and units must be uniform for
all independent variables under the "Vector COMMON" formalism.

4.3

Upon request of the Japanese Study Group codes for pions are
introduced in Dictionaries 28 and 29 for REACTION SF2 and SF3:

- 25 PI pions, unspecified
PIP pions positive
PIN pions negative
4.4

The BIB Keyword INC-SOURCE is adopted instead of N-SOURCE startingwith 1 January 1984. This applies to new transmission tapes; withrespect to the master files held at the centers, each center may
decide whether it keeps the old code or converts it throughout the
file.

4.5

The proposed LEXFOR entries for Errors, Dosimetry Reactions, andStandards were adopted with minor modifications (compare Memo
CP-C/1O2).

4.6

Bulky covariance matrices may have to be stored in a file separate
from EXFOR. NNDC will formulate a proposal.

4.7

The NNDC proposal to code correlation factors in the form
ERR-ANALYS(ERR1,1.)

is adopted; NNDC will formulate a proposed Manual update.
4.8

The CAJaD proposal of Memo CP-A/31 concerning the sequence ofGeneral Quantity Modifier in REACTION SF8 is adopted.

4.9

The Lexfor entry on energy resolution was confirmed.

4.10

After discussion of working paper 6 about frequent mistakes foundin EXFOR TRANS tapes, it was concluded that centers should
possibly improve their check programs to avoid such erros. It was
confirmed that the Multiple REACTION formalism must be used onlyin the cases mentioned in the Manual in Chapter 8 under REACTION.

4.11

It was recommended to compile in EXFOR proton resonance data as
requested by neutron data evaluators. The neutron data centers,
though presently not compiling such data, took note of thisrecommendation.

4.12

Tapes sent to CJD continue to require a dummy file of at least 100
records at the beginning of the tape.

4.13

CJD can accept a blocking factor up to 40.
centers.

4.14

All centers now use 9-track tapes.

4.15

All centers should continue to attach outside labels to the tapes
indicating contents and tape specifications.

4.16

CAJaD and NDS will transmit CPND data not only in the own series(A resp. D) but also revisions to B entries (previously KACHAPAG),
but both centers should co-ordinate with each other to avoid
duplications. NDS may also retransmit P entries (McGowan's fileconverted by KACHAPAG).

So can the other- 26 4.17

When data are Retransmitted at subentry level, CAJaD and CJD
continue to want to receive retransmissions of the entire entries.
NDS will take care.

4.18

Item 2 on Manual page 9.8 ("1 file per tape") is dropped. But if
there are more files on the tape this must be indicated clearly on
the outside label.

4.19

It should be noted that the Lab and Ref Dictionaries in the CINDA
books must not be used for compilation, because these are- incomplete (they contain only the codes occurring in the book),and- may contain superseded codes (if these still occur in the book).

- 31 National Nuclear Data Center
Status Report to theSeventh Nuclear Reaction Data Centers Meeting
October 17-21, 1983

I.

GeneralSince the last meeting of the Nuclear Reaction Data Centers in May 1982,
two new part-time nuclear structure evaluators have been added to the staff.
In addition, we have two visiting scientists from the People's Republic ofChina who will remain at the center for about one year working on nuclear
structure evaluation. We hope to be able to add some additional staff in theneutron data area by the end of the year.
We have installed a VAX-11/780 with 2 megabytes of memory, an RP07 disk
drive (456 megabytes), a TU 78 magnetic tape drive (125 ips, 1600/6250 BPI)
and 8 terminal ports. The system will be released to the users in January
1984 and will run in parallel with the DECsvstem-10 already in use. Equipment
diagrams for the NNDC computer systems are attached. In the coming year we
will be acquiring DISSPLA, VAX-11 DBMS and DATATRIEVE for the VAX and FORTRA77 capabilities on both machines. The Vector Automation Interactive Graphics
Terminal has become operational and a plotting system to be used in the
production of the BNL-325 book of curves has been implemented.
II.

WRENDAThe biennial review and updating of the U.S. Nuclear Data Request List
was completed in January 1983. Future reviews will be made on a four-year
cycle, although this does not preclude the inclusion of a few new requests inthe mid-review period.
III. Bibliographies
The normal CINDA and NSR activity has continued. Three supplements andone cumulative issue of Recent References have been published since May 1983.
The Nuclear Structure Reference file has been incorporated into the RECON
bibliographic retrieval system. The complete library was transmitted in
December 1982 and updates are sent every 4 months.
The input procedures for NSR have been modified to identify integral
charged particle data so that it is now possible to produce the index from the
NSR library. There is a gap in coverage of about one year between thetermination of the Charged Particle Bibliography and the entrv into NSR. We
hope to add the missing data to the NSR Library in the coming year.
The CINDA data exchange with NEA-DB has proceeded normalIv. In order tohelp insure that the NNDC and NEA-DB CINDA libraries remain identical, acomparison of the two libraries was done at NNDC and some, differences wereencountered. As a result, a complete reload was done by NNDC of the non-NNDC
entries from the NEA-DB Library. NEA-DB will reload the NNDC entries earlynext year.

SHI- 32 -A CINDA index was prepared for the 1983 DOE-NDC Progress Report and £„.
the IAEA Advisory Group Meeting on Basic and Applied Problems of Nuclear Level
Densities.
IV.

Data Libraries

In the periods from May 1982 through September 1983, 35 neutron datatransmission tapes (TRANS 1135-1169) were sent containing 123 new data sets
and numerous corrected data sets.
The conversion of the Area 1 entries to the REACTION formalism is
expected to be completed by the end of the year. A comparison has been madebetween the 80000 series SCISRS-1 conversion data and data transmitted from
Area 4. Data which were not identified as having been transmitted wereconverted to REACTION format and sent to CJD.
The new dictionary DBMS system was completed and is now in use for all
CSISRS library codes.
A new checking code was written which handles format and code checking,but does not yet include consistancy checking.
Most of the coding for the new library system (based on the REACTION
format) is completed. It will be implemented when the conversion to REACTION
formalism is completed.
V.

Evaluated Nuclear Reaction Data

Revision 2 to ENDF/B-V was released during the first half of 1983. The
revision contained new evaluations for Li and the W isotopes,
Rb,
Rb,
Ag andAg and revisions to 35 materials (14 major requiring review).
The ENDF processing codes have been upgraded to Revision 2 formats anddistributed.
Due to funding reductions, the schedule for oroduction of ENDF/B-VI hasslipped. Present plans call for the comoletion of the "standards" in the fallof 1984 and the completion of ENDF/B-VI in the fall of 1986.
The NNDC will continue to have responsibility for the production of
ENDF/B-VI and for the evaluations for the materials " Au,
U, Ni and Cr.
VI.

Nuclear Structure Data

T. W. Burrows conducted a three-week training session for nuclear data
evaluators in the People's Republic of China which was attended by 15
scientists from various institutions throughout China.
NNDC has continued publishing the Nuclear Data Sheets and issues throughVolume 38, number 3 have been sent to Academic Press.

- 33 -

VII. Customer Services
On-line retrievals from the CINDA and CSISRS data bases were initiatedwith Knoll's Atomic Power Laboratory to facilitate production of the Chart of
the Nuclides.
The request statistics for January 1, 1982 through June 30, 1983 are
attached.
VIII. Publications
The forth edition of "Neutron Cross Sections" Vol. 1, Part B, ResonanceParameters for Z=a61-100, will be issued by the end of this year. Work on
Volume II (Book of Curves) is expected to begin in early 1984.
The Proceedings of the IAEA Advisory Group Meeting on Basic and Applied
Problems of Nuclear Level Densities is in press and should be issued at theend of October.

ORGANISATION FOR ECONOMIC
CO-OPERATICN AND DEVELOPMENT
12th October, 1983
NUCLEAR ENERGY AGENCYNEA DATA BANK PROGRESS REPORT
Submitted to the 7th Meeting of
NUCLEAR REACTION DATA CENTRESI.

INTRODUCTION

The Data Bank has over the past eighteen months had a full workload,very well focused on its three main objectives : computer program testingand distribution, compilation of experimental and evaluated neutron data,
and the Joint Evaluated File project (JEF).
During this period, the JEF-1 starter file increased in size from 70 to
297 nuclides, and work started on the first (and simpler) benchmark test
calculations for fast neutron spectra. Computer program testing continued
at a normal level, with an increase in the number of packages sent out torequesters in non-OECD countries. Data compilation and customer service
effort has remained approximately constant over the last three years,
though the September 1982 Antwerp Conference resulted in a higher proportion of new data among those compiled in these last twelve months.
II.

NUCLEAR DATA SERVICES

Experimental data compilation and CINDA
The flow of neutron data for compilation was strongly affected by the
September 1982 Antwerp International Conference on Nuclear Data for Scienceand Technology. Most of the new data available in the Data Bank service
area which had not yet been presented was presented at that meeting: all
the available data from the Conference have now been compiled, leaving only
those papers for which no reply was received to our request for fur:her
information and data. Approximately 75 new EXFOR works were transmitted tothe other neutron data centres, with about 50 retransmitted data sets.
The EXFOR Data Base contains data from some 5600 "works" corresponding
to about 35,000 different nuclear'quantity measurements.
The number ofnew "works" added worldwide is expected to be about 250 for the year 1983.
The only clear trend to be seen in the Data Bank Member countries is astrong interest in evaluation of data, as expressed in the 3EF project.
The CINDA file has for some years shown a net growth of approximately
10,000 entries per year, and has now reached 19C,CC0 entries.
The 1902
Antwerp Conference itself generated about 850 new CINDA entries. It is now
intended to prepare a third archival volume in 1904, covering a five- or
six-year period beginning in 1977.
Revision work for the Data Bank's
service area will concentrate on the grouping together of different references to the same experiment, and on improving CINDA1s usefulness as an
Index to the EXFOR file.

- 42 The Data Bank prepared entries from its service area for the 1983-1984
issue of WRENDA: here again the level of activity was high. Out of acurrent total of 640 requests from Oata Dank Member countries, 54 were new
and 220 had been modified in some way.
Evaluated nuclear data files
Release of complete new data files has been somewhat slower than originally planned in the laboratories concerned, but all the major new files
received in full for inclusion in the disc-based retrieval system: ENDL-82,
JENDL-2 and KEDAK-4. The Data Bank has however received all the individual
evaluations selected for inclusion in JEF, and has also received fromHarwell and Winfrith the "thinned-out" files of pointwise data in ENDF-B/V
format, based on IAEA's recalculation with the revised RECENT program ofthese data for ENDF-B/IV.
Translation of KEDAK data selected for inclusion in JEF was made withthe help of ENEA Bologna, who provided the KTOE code and carried out anumber of calculations in cooperation with Data Bank physicists.
3oint Evaluated File (3EF) project
The Steering Committee for Muclear Energy gave its approval in October
1981 for the one-year pilot project which resulted in the production of thecurrent DEF-1 file containing data for 275 nuclides, during 1982. In October 1982 the Steering Committee approved a three-year second phase project
for the benchmark testing of JEF-1 and the assembly of a JEF-2 file, revised and including new evaluations in the light of the results obtained in
testing JEF-1.
The main source of uncertainty in starting benchmarking work for 1983
has been the accuracy of resonance representation by the different versionsof the processing codes for ENDF/B-IV and V data. A comparative study
organized by IAEA Nuclear Data Section has done much towards removing the
major discrepancies between the different codes available to the Data Bank.
A first stage set of calculations for the Karlsruhe zero-dimensional
benchmarks, and for the simple one-dimensional benchmarks recommended by
the JEF Scientific Coordination Group, have given encouraging results.
These calculations will be continued.
Customer service for neutron data
During 1982 (January to December) 176 requests, equally divided between
experimental and evaluated dat.a-, were answered for 97 requestors. This
figure represents about one request per working day, a level which has held
over the past ten years except for a peak in 1978-1979 at the time whensome parts of ENDF/B-V were being released outside the United States. Requests are carefully defined in order to eliminate irrelevant data sets,
but nevertheless 5 1/2 million logical data records were sent out over thisyear. Besides these data, which were mostly retrieved from the data bases
or copied from magnetic tapes, 50 group cross-section libraries for various
applications were distributed.
Plots of data requested can be supplied
from the VERSATEC plotter installed during the year, and in particularcomparisons of experimental and evaluated data. Use of this service has
been growing only slowing among general requestors so far, although theplotting facilities has been heavily used in preparing for specialists'
meetings and in preparing data for review in the JEF project.
About 130 requests for data were filled in the first nine months of1983.

- 43 Charged particle and nuclear structure data
The modest service offered on nuclear structure data, with copies of
the Evaluated Nuclear Structure Data File (ENSDF) and its retrieval programs held on the CISI computer system for the benefit of network users,with alternatively the possibility of making requests directly to the Data
Bank, has generated a small number of requests for data to be sent out fromthe Data Bank, plus regular use by the two French groups concerned of theretrieval programs through CISINET.
The program for plotting detailed
level schemes has been implemented, and is fairly well used.
Severalrequests were answered for charged particle cross-section data.
III. COMPUTER PROGRAM SERVICE
In routine program testing, 1C8 programs were master-filed in 1982,
while 1135 program packages were sent out in answer to requests. 246 ofthese went to non-OECD countries, a slight increase on 1981. The proportion of programs already tested at the time the request for them was received continued to rise, and has now reached 80?o : this figure is probably
the result of improved information about the programs available, and the
new series of program abstract publications was completed by the issue of athird volume (programs received from the Radiation Shielding Information
Centre, Oak Ridge).
IV. BENCHMARK TESTING OF COMPUTER CODES AND DATA
1.

Nuclear model code intercomparisons

A preliminary report pa the first exercise in this comparison (coupledchannel calculation for U) compared only the results obtained with different versions of the JUPITOR code.
A more recent analysis includes
comparisons also with ECIS-79, CHUCK-2 and CCROT/CCVIB, which give generally good agreement.
qanalysis of the spherical optical and statistical model exercise on
Co
is now complete and is being distributed as NEANDC-152"A"/INDC(NEA)4
and to participants.
Pre-equilibrium conditions were included in someparticipants' submissions to this problem, but were not discussed in thepresent report. A supplementary exercise on the charged particle opticalmodel is being distributed to participants, since this may help resolve
some ambiguity in the choice of parameters for the charged particle
reaction channels in the statistical model.
Specifications for the exercise on pre-equilibrium models were sent out
in February 1983 to participants in the previous exercises, and it is hoped
to receive results by the end of,the year.
2.

Nuclear data processing codes

The two major series of codes for transforming evaluated data in ENDF/B
formats into a point-by-point representation and thence into group crosssections have been subject to considerable revisions over the past twelve
months, while in parallel a benchmark exercise organised by IAEA Nuclear
Data Section is verifying the performance of different codes used for the
successive steps in this process.
The validity of the NJOY system isparticularly important to the Data Bank because this system is presently
being used for the production of the pointwise representation of thecross-sections in the resonance region in the point-by-point version of the
JEF file.

- 44 Two members of Data Bank staff have contributed to this benchmark, inparticular with calculations of 620-group cross-section sets for ENDF/B-V
dosimetry data using the IBM version of NJOY.
3.

The determination of average resonance parameters

This benchmark was carried out with two successive sets of resonanceparameters. After the first exercise had shown unexpectedly large discrepancies, both between different codes, and between each code and the correct solution, a second exercise was broken down into linked problems ofincreasing complexity in order to help isolate the inadequacies in thecodes used.
Following a workshop, and a "blind" test in which a new member of theData Bank staff followed the authors' documentation to the bitter end, thereport on the study was published as NEANDC-16C-U (Data Bank Newsletter No.
27).

PUBLICATIONS DURING 1962 AND THE FIRST PART OF 1983

Regular issues of CINDA (prepared at NEA Data Bank for publication by
IAEA), News from NEA Data Bank, the Neutron Nuclear Data Evaluation Newsletter, and two issues of the Newsletter/Bulletin were distributed in 1982,
with one more in 1983 and another in preparation.
Two important occasional publications were distributed :The fully revised RSIC (Radiation Shielding Information Center, Oak
Ridge, USA) computer program abstracts, with first supplements to thefull collection (both US and NEA-IAEA) and a KWOC index.
-

The proceedings of the November 1982 NEANDC Specialists' Meeting on
Fast Neutron Scattering on Actinide Nuclei.

The full set of three volumes of Computer Program Abstracts (NESC,
NEA/IAEA and RSIC) was made available on microfiche, while the same abstracts were made available on magnetic tape to several centres.

Staff, budget, programme

The staff of the IAEA Nuclear Data Section (NDS) as of October 1983
is shown on the next page. During the past 18 months, there were only
few changes.
N. Kocherov was replaced by V. Piksaikin from FEI Obninsk, USSR.
D^
Gandarias-Cruz from Cuba joined the Section working as the main Exfordata compiler, filling the post that was vacant after N. Payday left theSection. M. Mehta from BARC Trombay (previously INDC member from India)
joined the~Section working primarily on research contracts and researchcoordination in developing countries. He filled the post that was vacant
after R. Langley had left.
The difficult budget situation of the Agency continued. For the time
being it seems that the nuclear data programme can be continued at zero
growth. But a longterm prediction is hardly possible. The number ofrequests and the volume of requests received from developing countries
continue to increase, though there may be some fluctuations.
This
depends, on the one side, on the development of nuclear data related
programs in the developing countries, and on the other side on the ratethat new data files become available. The People's Republic of China has
become a member of the IAEA, and this will bring additional workload to
the Section in both, data compilation and the data centre services.

2.

CINDA work at NDS (ML)The
coverageofjournals
is now
satisfactory, althoughthesubscription to some journal titles was cancelled by the IAEA library forbudgetary reasons. However, co-operation with other libraries together
with abstracting and indexing services ensures the current awareness of
CINDA-relevant publications for NDS. The coverage of reports depends on
delays in availability of reports (full size of microfiche), but
CINDA-relevant papers are usually not missed. Greater emphasis is given
to blocking and cleanup for the 1984 archival issue.
More than half of the CINDA work at NDS (not considering CINDA bookproduction) is spent on area 4 entries. This is mainly due to the factthat CJD does not maintain its own CINDA file. Therefore all assignmentof block-numbers for new entries, reblocking and revisions of old entries
is done by NDS, the judgement of literature comprising the same work
involving frequently the consultation of original Russian literature at
the library.
Literature coverage by CJD and coding of CINDA entries
requires improvements to be discussed separately.
The revised book production introduced with CINDA82 has proven to be
successful, saving a weektime in the
preparation
until
final
publication. Another innovation - the shortened format for the CINDA
supplement - will be implemented for the 83Supplement in the form
outlined in memos 4C-3/263 and 4C-3/266.

The EXFOR System

The EXFOR rules remained stable and the new formalisms for the codingof uncertainties and correlations did not create any problems.
The formal correctness of the EXFOR transmission tapes continued to
improve though some further improvements are essential (they will be
discussed separately).
The main problem remains the completeness of compilation and delaysin the shipment of magnetic tapes, particularly with area 4.
The efforts to gain additional data
centers
for
the
EXFOR
cooperation, were partly unsuccessful, partly successful. There was somehope that the work by Kachapag could be continued elsewhere in the Fed.
Rep. of Germany.
There was active interest at the Institut fiir
Radiochemie at the University of Koln (Cologne), however we just heardthat this institute is likely to be closed down.
In Japan we had intensified contacts with the "Study group" whichtransmitted two trial Exfor tapes with charged-particle nuclear data,
mostly differential. These contacts will be further intensified.
We welcome particularly that a new Japanese group from RIKEN isrepresented at this meeting for the first time in order to join the Exfor
cooperation in the field of production cross-sections for radioisotopes
for biomedical purposes.
3.1

EXFOR TRANS tapes received (OS)The latest TRANS tapes received from NNDC, NEA-DB, CJD and CAJaD are
1168, 2094, 4048 and A010, respectively.
We continued to inform theoriginating center of the mistakes detected by our check program. The
correcting of incoming TRANS tapes still absorbs some manpower, andfurther improvements of EXFOR check programs at all centers are a matterof priority. A summary of frequently occurring errors where NDS asks formodification of the respective centre's check program is given in a
separate Working Paper.
Another working paper lists the pending
retransmissions requested by NDS.
NDS used to distribute corrected versions of Area 4 TRANS tapes tothe other centres. The number of errors found in the last 3 tapes
received recently, TRANS 4046 through 4048, was however so small that we
see no need to continue this practice. We should like to congratulate
CJD for this improvement. With TRANS 4048 we had a problem in reading
the tape, which means that an entire block of records of subentry
40059.002 is missing in our master file.
Therefore we ask CJD toretransmit to NDS this subentry (or the entire tape TRANS 4048, whateveris easier).
3.2

EXFOR/CINDA Dictionaries (OS)Since May 1982, 8 dictionary updates and 3 transmissions of the entire

- 48 -

dictionary file have been made; the latest transmission (TRANS 9046) from
October 1983 is in the mail at the the time of the present meeting.
Dictionary 27 (Nuclides), 36 (Quantity, Reaction SF5-SF8) and 7 (Books
and Conferences) were updated most frequently. An important progress was
the obsoletion of the keywords of the ISO-QUANT family. Separately fromthe regular dictionary updates, NDS prepared a draft version of the new
dictionary 7 (introduction of short expansions for books and conferences,
as agreed at the last NRDC meeting) and sent it to NNDC for comments.

EXFOR Compilation (KO, DG)

EXFOR 3 Series:

During the period May 1982 to September 1983, 38 new EXFOR entries
were transmitted originating from the following countries:

The somewhat low number of compilation is due to temporary shortageof manpower and to training of a new compiler. Considerable efforts weredevoted to many retransmitted entries, due to corrections of the large
volume of Lucas Heights capture data, and due to additional publications
or authors' comments after the first compilation.
The revision ofseveral entries with more than 18 data columns to the accepted maximum of
18 was finished but absorbed more manpower than anticipated.

After the People's Republic of China becoming an IAEA member state,
it is expected that Chinese data will become available faster.
4.2

EXFOR V-Series:

evaluated neutron nuclear data

NDS continues to compile selected important evaluated neutron data in
the EXFOR V-Series, if such data are not convenient for compilation in
ENDF/B format. Due to shortage of manpower and other assigned duties,
however, there was no entry for the V-series in the past 1.5 year period.
4.3

EXFOR D-Series;

charged-particle nuclear reaction data (CPND)

A remarkable result during this period was the EXFOR compilation ofmany numerical data (including private communications) on the ^Li(p,n)
reaction, which had been originally collected by H. Liskien, CBNM. The
resulting entries are D0031 to D0041.
Similar compilation work willcontinue as workload permits.
NDS also compiled CPND data for radioisotope production for medical
purposes in 5 EXFOR entries. We are looking forward that this work will
be continued by the RIKEN group, Japan.
4.4

EXFOR G-Series:

photonuclear data

The second EXFOR-G entry (G0002) was compiled by NDS.
This isphoto-fission and photoneutron cross section for Np-237, a topic coveredby CINDA. Neutron capture gamma rays with energies between 5.4 and 10.8
MeV were used as the incident gamma rays. Due to manpower restrictions,the compilation of photonuclear data has low priority.
4.5

EXFOR P-Series;

McGowan's CPX file

Kachapag received McGowan's old CPX file, selected those data thatwere still useful, checked these data against publications, and converted
them to the KACHAPAG internal format for publication in the "Physics
Data" handbook.
This file was converted by NDS to EXFOR format.
Unfortunately, it could not yet be transmitted because we are stillworking on correcting some mistakes that we found in the data.

5.

Evaluated data

The topic of ENDF/B format compilation and checking had been treatedextensively at the last NRDC Meeting in Vienna. Since then the ENDF/B
checking capabilities were improved by operating the code FIZCON and byimproved graphical plotting facilities. The 1983/84 versions of the INDL

- 50 -

files will not include many new evaluations but many revisions to earlier
evaluations. The main subfiles of INDL are
INDL/V
1RDF
INDL/AINDL/F-various evaluations
dosimetry reactions
actinides
fusion reactions for INTOR

A continuing problem concerns those evaluatedcoded in the ENDF/B format for different reasons:data that cannot

bedata at high neutron energies
data with Reich-Moore parameters
the new Livermore library
the need for having a joint format for neutron data and chargedparticle data as required for some special purpose data files.

6.

WRENDA (VPi)

WRENDA 83/84 is being published with some delay because of latereceipt of KFK requests. Meanwhile the updated WRENDA master file has
been produced.
The edited format for publication and several special
listings of modified, satisfied, or withdrawn requests are being prepared.

7.1

Publications

Fission Product Nuclear Data (FPND) (ML)

Issues 8 and 9 of the annually published report series "Progress in
Fission Product Nuclear Data" were distributed as INDC(NDS)-130 (1982)
and INDC(NDS)-143 (1983).
Issue 8 contained 166 pages of contributions and a total of 186
pages.
Due to a cleanup of contributions, the size of issue 9 was
reduced to 151 pages of contributions and a total of 172 pages. The
number of countries contributing to the progress report has increased
from 12 in the first issue (1975) to 30 in the 8th issue, the number of
institutes from 32 (1975) to 100 (9th issue).
The 10th issue is envisaged to be published in July 1984.
asking for contributions will be sent out in April 1984.
7.2

Circulars

Handbook on Nuclear Data for Safeguards (ML)

NDS, with support from the Department of Safeguards of the IAEA, isplanning to issue a handbook on nuclear data for safeguards.
This
handbook should contain sets of "best" evaluated nuclear data together
withcarefully
assessed
uncertainties,
currently
availablefrominternational nuclear data files.

- 51 -

Only such data will be included that are used or will be used innuclear materials safeguards. If required, some non-nuclear microscopic
as well as macroscopic data may also be included, if such data are
available. In order to define the contents and scope of the handbook, aquestionnaire together with a tentative list of data was sent out tosafeguards experts in several IAEA member countries.
After collection of the replies the data to be included in theplanned handbook will be defined and experts will be asked to recommend
the best presently available files or tables containing the requested
data.
The data adopted will then be collected in the form of acomputerized data base for the production of the handbook.
The main potential users of this planned handbook are scientists
working on the development of safeguards methods and analyzing andevaluating safeguards data.
7.3

Standards

A handbook containing the INDC/NEANDC standard reference file is inprint.
7.4

Nuclear Activation Data Handbook

The Nuclear Activation Data Handbook, a successor to the handbook
published in 1974, is in progress and scheduled to be printed in 1984.
7.5

INDC reports

Please refer to the document INDC(SEC)-85 giving an index to all INDC
reports.
They continue to include progress reports from various
countries, reports of NDS meetings, translations into English fromselected USSR publications, and some original works from the NDS service
area.

8.

Customer Services

The services of NDS are advertised to its customers by the "IAEA
Nuclear Data Newsletter" of which about 2000 copies are distributed about
twice a year in intervals that depend on the rate at which important newmaterial is received at NDS. Attached to the Newsletter is a return
postcard by which data, reports or other information can be requested.
In order to improve the data services offered to NDS customers, thereceipt of new data files or updates to older files, initiates a searchof the standing requests filed in the computerized Request Log, resulting
in the despatch of the new data to the requestor.
Documentation reports, issued in the IAEA Nuclear Data Services
report series (with report code IAEA-NDS-...), which describe the format
and content of data files, are now available for all data files kept at
NDS. These reports, kept up-to-date and continuously improved, are sent
together with the date files requested from NDS.

- 52 -

Data retrievals in the EXFOR, ENDF/B and some other formats areavailable in "standard format" for computer processing, or in "edited
format" for easy reading, either on tape or in the form of listings.
Graphical computer plots can also be provided.
These services areprovided primarily to the NDS service area.

Data Request and Dissemination Statistics

During 1982, NDS has received 713 requests, which amounts toapproximately three requests per working day. For the definition of a"request" the reader is referred to report INDC(NDS)-124, p.18.
Averaged over the years 1980, 1981 and 1982, NDS received an annual
average of 588 requests. Of these:
9.9 % were for experimental data
25.2 % were for evaluated data
7.6 % were for data processing programs, and57.3 % were for reports.
With regard to request origin,
7.0 % originated20.6 % originated67.3 % originated
5.1 % originatedin area 1 (USA and Canada)
in area 2 (Western Europe and Japan)
in area 3 (NDS service area)
in area 4 (USSR).

Request statistics for each of the considered categories, andstatistics showing the total number of requests handled by NDS for eachof the last 18 years are given in Table I. Figure 1 shows the request
statistics since 1965 in terms of number of requests per year averaged
over 3 year periods (i.e., the number for 1982 is the annual average over
the years 1980, 1981 and 1982).
Data dissemination statistics show what NDS has sent out as a resultof requests received; numerical data are normally quantified in terms of"data sets".
A "data set" is defined as a set of numerical data of a given typefor a given nuclide in a given energy range which resulted from a
specific data measurement or evaluation. For evaluated data, a data set
comprises all data given under one "MAT" number in a given evaluated datalibrary; for EXFOR, a data set comprises all data combined in an EXFOR
sub-entry (excluding the first BIB subentry). Averaged over the years
until 1979, and considering both experimental and evaluated data, a data
set comprises an average of 184 data points or data records which would
represent a typical data set. As shown on Figure 2, the number ofnuclear data sets distributed per year (including experimental andevaluated data) has increased exponentially during the last 18 years.

10. Programming and Systems Development

10.1

GeneralThis period has been a time of consolidation and improvement under
the present Agency policy of "zero growth" budget, coupled with the everincreasing size of the nuclear data libraries and number of requests fromusers for nuclear data. The only way in which it will be possible tomaintain the quality of the data libraries and promptly respond to data
requests will be by increased efficiency in the utilization of computerequipment.
In line with the above remarks, in an attempt to minimize the amountof manual data checking by NDS physicists, the data checking programs forevaluated data (in the ENDF/B format), EXFOR, CINDA and WRENDA have beensignificantly updated to improve automatic error detection. In addition,
graphic output has been extensively used to detect errors in evaluateddata. Work on the computation format for experimental data has continued
and graphic output of experimental data will be available in the near
future to allow error detection.
In order to minimize the amount ofeffort and response time to answer data requests, the index files to theexperimental and evaluated data files have been improved.
10.2

EXFOR Programming

The current EXFOR file maintenance programs, used to update thelibrary and retrieve data from the library, may be considered up-to-dateand require only a minimum of maintenance. The EXFOR checking program
has been significantly improved to automate error detection. Work on thecomputation format has continued with the aim of developing a programsupport package to allow tabular and graphical presentation of a variety
of experimental data, all in a common, comparable set of units.
10.3

Request and Dissemination Log System

The Request Log is designed to monitor the arrival of requests at NDS
and the processing of requests through NDS, in order to insure that eachrequest is answered promptly.
The Dissemination Log is designed tomonitor the flow of information out of NDS. Together, the request anddissemination logs allow us to determine what types of information are
required by our users, and to quantify the output from our centre (seestatistics under Section D.4.).
During this period the request and dissemination log system was
improved to simplify use and improve the types of statistics that may beobtained from the system, e.g., request patterns by isotope, type of
data, reaction.
10.4

WRENDA

The WRENDA file maintenance program system is essentially complete;minor improvements were introduced during this period, in particular

- 58 -

concerning retrieval criteria and output sort orders.
The
checking program was updated in order to improve error detection.
10.5

WRENDAThe Data Index System

Instead of searching the large numerical data files maintained by
NDS, many requests can be more economically satisfied by searching
relatively small data index files in order to determine which datasatisfy a given request. A Data Index System which indexes all of NDS's
data files is being implemented. At present entries into the Data Index
System are performed automatically for all EXFOR data when a TRANS tapeis merged into our EXFOR master file.
For EXFOR data it is possible to retrieve data by reaction, author,
institute, energy range, etc. In the case of evaluated data, retrievals
are currently performed in two steps: retrieval of whole evaluations
using the Data Index System, and selective retrieval by reaction using
specially designed retrieval programmes. The index system is currently
being extended to automate the handling of evaluated data, particularly
those evaluations in the ENDF/B format.
10.6

Profile System

NDS maintains a PROFILE system, consisting of a computerized file ofthe names, addresses and the areas of interest for each of the centre's
correspondents. Areas of interest are described by the use of one ormore distribution/interest codes. This file is used routinely to produce
reports, to selectively retrieve address lists, or print address labels
for the mailing of publications and correspondence. During this period
the PROFILE system has been extensively modified in order to improve theflexibility of the use of the address field.
There are currently 5 300 names and addresses stored in the PROFILE
system master file; last year approximately 600 names were added, andabout 200 corrections and/or changes per month were made.
10.7

CINDA Programming

The system of CINDA programs that are operational at NDS is used tocheck new or revised entries, retrieve from the master library andproduce the CLNDA book.
Production of the CINDA book requires two
steps:
format conversion to a form that is acceptable to thephoto-type-setting process, followed by the actual photo-type-setting.
This system of computer programs has remained rather stable over theyears and only minor improvements were done to improve error detection.
10.8

Evaluated Data Processing

The growing number of evaluated data libraries (e.g. UKNDL, KEDAK,
ENDF/B etc.) requires that a growing number of programs be maintained andoperated at NDS in order to allow for file maintenance, retrieval,checking, and correction of evaluated data.
In addition, in order toallow the evaluated data to be used by our customers, the data handlingprograms are distributed with the data.

- 59 -In order to avoid duplication of effort, programs developed at otherdata centres are adopted for use at NDS whenever possible. At present
NDS maintains and distributes to customers only elementary file handlingprograms. All requests for more complex programs, such as multigroupprocessors, are referred to the IAEA Liaison Officer at the NEA Data Bank.
During this period additional computer programs were implemented at
NDS in order to allow the introduction of procedures to improve thereliability of the evaluated data which are disseminated by NDS. In
particular, format and physics checking codes in conjunction with graphic
output have been used to significantly improve the evaluated data files.
When minor problems are encountered, the format or data can be correctedon line. When major problems are encountered, they are reported to theoriginating evaluator or data center.

PROGRESS REPORT

1.
Since May 1982 CJD 'has transmitted into other centres themagnetic tapes with TRAITS 4044 - 4048 containing 52 new entries
and 14 corrected entries. The total number of the transmitted
entries is 532.
2.
In 1982 the work on putting into operation the programmes
checking EXPOR format has been completed. The programmes werereceived from Nuclear Data Section and adapted to the computer
EC 1033* That required to do some changes in programmes becauseof differencies in programming languages and computers, to write
additional subroutines. The TRAITS 4046 - 4048 have been checkedusing the programmes mentioned. The checking programmes gave us
possibility to begin the checking and correction of the wholearea 4 32F0R library. For the time being the entries with code
REACTION are in process of correction.
3* In CJD the following programmes were put into operation andare used for the work with data files in ENDS'/B format:CHECKER-5,
FIZCQN, PSYCHE, CRECT, DICTION, MERGER, PRIN2, PRBTTE, SUIJRIZ,CATALOG, RESEHD, (LINEAR + RECENT), GROUPIE, SIGMA 1, INTER.
A short report about the functions of these programmes will
be published in the nearest issue of "Jadernye konstanty1.'
The programmes for the production of group constants
GRUCON (FBI), NJOY and RECENT are also put into operation andthe comparison of the results obtained by means of these programmes was made. The essential differencies in results are not dis covered*

The CINDA on magnetic tape is used to retrieve information.
The program was written for this purpose.
5.
In FBI the work on the evaluation of fission product capture cross section has been completed ( for about 30 isotopes).
The results of this work are presented to the Conference on
Neutron Physics, in Kiev (1933), and also published (Partially)in "Jadernye Konstanty" ( 1, (50), 1983 ) .

- 62 -The reevaluation of the cross sections for natural Cr and
Cr isotopes was done. The data are in process of putting on
magnetic tape and checking. V/e suppose to complete this work
earlynext year.
The results of the evaluation of neutron inelastic scattering cross sections of Cr and the comparison of these resultswith the SHDP/B data are published in "Jadernye konstanty"( 4 (48), 1982 ) •GJD continues the work on the analysis of available eva luated nuclear data files* The objective of this activity is todevelop proposals for improving files and to give recommenda tions on the use of files in evaluated data libraries. The
great attention was paid to analysis of data files for the actinide and fission product isotopes, some structural nxaterials
and dosimetry reaction data. The results of this analysis should
be useful for development of international evaluated datalibraries.
6.
Developing evaluation methods CJD paid a great attention
to the method of simulteneous discription of level density,
fission cross section and excitation functions of (n,xn) - reactions. The direct process contribution to the spectra of neutron
inelastic scattering was thoroughly investigated.
7.
The WREHDA - 81/82 requests from USSR have been revised andapproved for the next edition. CJD supposes that the more c e r tain definition of required accuracy should be made inall

Usachev's requests.
8.
After the last meeting the collections VA1TT, series "Jadernye Constanty" HN 46 - 53 and the Handbook "The threshold reac tion cross sections induced by neutrons" (Snergoizdat, 1982)

SURVEY OF WORK BY CAJaD -ON THE COLLECTION AND DISSEMINATION OF
CHARGED PARTICLE NUCLEAR DATA
(Brief report to the Seventh Conference of CPND Centres)
G.M. Zhuravleva, N.V. Timofeeva,
and F.E. Chukreev

This review covers the period from May 1982 to October 1983.

1.

Over this period CAJaD prepared and fed into the nuclear data center

network magnetic tapes A008, A009 and A010 containing numerical datafrom 57 publications both by Soviet and foreign scientists.
2.

The vast majority of these 57 publications dealt with the measure-ment of reactions of importance to controlled thermonuclear fusion andthe preparation of radioisotopes.
3.

The changeover to the compilation of both Soviet and foreign re-search data presented CAJaD with new problems that had not existed
before.

As you know, when compiling Soviet research data we aim at

acquainting the authors of the articles with the prepared compilation
and at pointing out inaccuracies that are both the fault of the compiler
or the authors themselves and the publishers.

When preparing data from

Soviet authors for magnetic tape recordings we try to ask the authors
for further details of the experiment and to clarify its accuracy.
Almost all our attempts to obtain information of this kind from foreigngroups have proved fruitless.

Our requests go unanswered.

The onlygroup which has replied to us is Michel's group at Cologne University.
4.

Broadening of the scope of our compilation activities has brought

to light another fact that is new to us - we have discovered that alarge number of different measurement units are used in articles by foreign authors.

For example, for thin targets use is made of the normal
2
cross-section (m barns or ^ barns); yields (Ci/na-h'g/cm ) and(Ci/ya'h'MeV) and so on.

This variation in unit systems not only ham-pers the work of making recordings on magnetic tape, but what is more
important, it creates difficulties in subsequently applying the data inpractice.

*/

The Nuclear Data Section would do well to take upon itself

USSR Nuclear Structure and Nuclear Reaction Data Center.

- 64 the task of addressing the editors of the relevant journals and thereferees and drawing their attention to the unnecessary "variety" ofunits of measurement.

The Section's authority is quite considerable

and its proposals are always given attention, so it is to be hoped that
this initiative on its part would be valuable.
5.

Over the period under consideration CAJaD answered roughly 80

nuclear data inquiries.

V.V.Varlamov, B.S.Ishkhanov, V.7. Surgut an ov, A.P.Chernyaev.
Since early in 1982 till mid 1983 the Centre for Photonuclear
Experiments Data of the Institute of Nuclear Physics of Moscow
State University (CDFEO' has carried out the following tasks:
1. The magnetic tape MOO3 including EXFOR-data from 20 papers of Soviet authors has been prepared and handed over to the
IAEA funds (through GAJaD of the USSR State Committee on the Useof Atomic Energy),
2. The Index "Photonuclear Data 1976-1980", containing systematized information on experimental photonuclear papers publishedduring these 5 years in the periodic scientific journals in the
USSE and abroad, has been completed,
3. A regular issue of the annual CDPE Information Bulletin
N 5 "Photonuclear Data - 1981" has been published and distributed,
the preparation for publication of Bulletin N 6 "Photonuclear Data - 1982" completed,
4. Within the framework of the program of preparation of thematic reviews of photonuclear data, the Information Review on thephotofission of heavy nuclei has been prepared; the Review examines the present-day situation with the yields and cross sections
for the reactions of photo- and electrofission, the ahgular, energy, mass, and charge distributions of fission fragments, the characteristics of fission neutrons, the properties of spontaneously
fissioning isomers.
Digital data from 165 papers published during 1952 - 1982 in
the USSR and abroad have been tabulated and recorded on the magnetic tape in the EXFOR.
5» In collaboration with the Centre for Nuclear Data of theLeningrad Institute of Nuclear Physics of the USSR Academy of
Sciences, the software for operation with international file ofbibliographic information on nuclear structure NSR has been adapted to the Unified Series computer of CDFE.
6. The software has been developed for operation with thedata recorded in the formats: EXFOR, ENSDE1, NSR, and BIB (the internal format of CD3TE).
7. A magnetic tape has been prepared which contains data on
the characteristics of radionuclides prodused in the photonuclear
reactions. It is intended for the automatic information provision

- 66 -

for studies in the field of the ^-activation analysis. The tapecontains the information on the energies of ^-transitions, typesof reactions in which radionuclides are formed, their halflifes,
etc. The adopted format and the developed software make it possible to find, from certain given parameters (or ranges of theirvariation) other parameters, thus significantly facilitating theidentification of experimental ^-spectra and raising the efficiency of the elemental and multielemental analyses.
8. In the last period CDFS has met about 300 requests forbibliographic information, information bulletins issued by theCentre and about 80 requests for digital data recorded in the various formats.

Progress Report on Nuclear Data Activitiesof the Data Centre of theLeningrad Nuclear Physics Institute
I. Kondurov

The Data Centre of LNPI is not involved directly in compilation or
evaluation of reaction data. The main direction of the activity is
nuclear structure data.
The Centre continues to produce keyword
references of Soviet papers on nuclear structure and reactor data to be
included in the NSR f i l e . 250 references have been included in the f i l e
and published, about 500 are ready to be sent.
A-chain evaluation: A=134 is being published in Nuclear Data Sheets,
A=133 is being prepared to be sent to Brookhaven.
Close to the subject of this meeting is a work done by the Centre on
neutron activation analysis data. We have a programme that extracts
decay data sets of all radiative nuclei produced in y-reaction and theirdaughter nuclei from ENSDF. Then one can calculate a short l i s t of
Y-rays of this decays taking into account the conditions of irradiation,
delaying and measuring of y-radiation.
This l i s t can be used whenanalysing measured spectra manually or automatically.

- 75 WP6Frequent and/or important errors where Improvement of check programs
is recommended (O.S.)

Area 1 entries-

Data lines out of order (independent variables are not monotonic).
BIB section MONITOR code missing when MONIT is given in DATA section.
NOSUBENT requires '*' in col. 80.
Wrong nuclide given under DECAY-DATA (can probably not be checked byprogram).
Spontaneous fission v should be coded (O,F),,NU rather than (N,O),,NTJ(which was used several times).

Area 2 entries
The second REACTION code of a REACTION combination, if not fitting inthe same line, must start in col. 12.
EN, EN-MIN, EN-MAX must not be given under ERR-ANALYS.
explained under N-SOURCE or INC-SPECT.
-

They may be

Reaction products are sometimes wrong or missing.
No codes allowed under INC-SPECT.

Area 4 entries-

The incident energy (EN or equivalent) must always be present in the
COMMON or DATA section, except for nuclear quantities identified by azero in the projectile field SF2 under REACTION. In particular for
average resonance parameters, level spacings etc., the range EN-MIN
to EN-MAX was frequently missing.
For resonance parameters, REACTION SF4 (product nucleus) should beblank unless an isomer has to be coded.

Area A entries-

Missing or wrongly used commas and decimal points in DECAY-DATA codes.
The exponent in E-format numerical values must be right-adjusted in
its respective field.
In MONIT-REF codes, an accession-number in the first field must
always include a subentry number. Refer to subentry 1 if no specific
Subentry can be used.

- 76 -

Entries from all areas
Subentry 001 often contains information that, contrary to the rules
does not apply to all subentries.
In particular, "ERR" column
headings were occasionally explained in subentry 001 although they
did not occur in all following subentries.
Reaction products were found missing in the REACTION coding string,
mainly for scattering data or monitor reactions.

Concluding remarks
Some of above items are serious:
When the REACTION coding string is not perfect, this may have theresult that the data are missed in retrievals. The Exfor user will
get an incomplete retrieval.
-

When the column^headings or the numerical data formats or the
DECAY-DATA coding are not perfect, format conversions to "Edited
Format" or "Computation Format" will blow up or will produce mistakes.
When DATA records are found out of order (independent variables not
monotonic or values repeated), the user has reason to mistrust thedata.

The following is important to realize:
table is repeated, this may be

or, as frequently, by mistake: a data record had been corrected andthe superseded record, by mistake, was not removed from the file.
Consequently, repeated energy values (which are easy to detect) are

user will mistrust the data.

Repeated independent variables (or independent variables out of order)
are essential to be included in check programs.
Other items mentioned in above lists of errors are obviously lessimportant but all of them use up manpower when they are encountered.

Comments on the Status of Neutron Data Exchange
Dosimetry Fission Reactions
For several years, NNDC has been concerned about the flow of EXFOR
compilations from the USSR Center at Obninsk, CJD.
The transmittals
which have been received have not come at reasonably regular intervals
and have required considerable effort on our part to correct both format
and content errors.
Our approach to analyzing the problem was to look at CINDA and the
EXFOR lines in CINDA for Area 4. In so doing, we found extensive errors
and gaps on CINDA and so have resorted to a CINDA-EXFOR intercomparison.
We present here the observations and conclusions of this intercomparison
for six important dosimetry fission cross sections. We also reviewed
other reactions but because of the sparcity of information, no further
significant results could be obtained.

Observations
1.

Many data sets which are referenced in CINDA and which CINDA lists as
containing data tables are not compiled in EXFOR. (There are 25 suchdata sets in CINDA).

2.

There are 15 data sets in EXFOR for which no CINDA block exists.

3.

There are numerous references in EXFOR which are not entered
CINDA, although the CINDA block for the experiment does not exist.

4.

For many of the data which are coded in EXFOR, CINDA contains later
reference which are not cited in the EXFOR data set.

5.

There is only one CINDA reference with a publication date later than
1980.

6.

Many of the data compiled in EXFOR are duplicated, sometimes two or
three times.

inConclusions
1.

There may be many data sets which are not referenced
EXFOR.

2.

Many of the data sets compiled in EXFOR may be out of date.

3.

We will have to review carefully the USSR data in EXFOR before using
it in the publication of the "Book of Curves".

4.

There should be a review of the
publication of the archive volume.

CINDA matters of area 4
by M. Lammer, October 1983

In order to reduce NDS workload
items need to be discussed.

on area

4 CINDA entries, several

Listed below are 3 main problem areas comprising most of the extra
work at NDS, and a 4th item summarizing minor problems.
1)

Incomplete coveragescanning at NDS.

ofliterature,requiringaduplicationfo

2)

So far, CJD does not maintain its own area 4 CINDA file. Therefore,
all the blocking of new entries and revisions of all entries is done
at NDS.

3)

The contents of CINDA entries submitted is not sufficiently reliable:
in most (!) cases revisions by NDS are necessary. As NDS covers thetranslation series, and does the blocking for the translation CINDA
entries, there is a continuous cross-check showing too many defaults
in CJD entries (e.g. wrong quantity codes).

4)

Minor problems:
the formal coding rules are not fully observed;
new codes are sometimes introduced (mainly for conferences)
without accompanying explanation required for CINDA tables and
EXFOR dictionaries;
coverage control entries are mixed with other CINDA entries andnot coded on the special ZZ-sheets designed for this purpose.

ad 1)
Only the more important journals of area 4 and "YK-" arecovered; this is a fraction of the area 4 journal series listed in EXFOR
dictionary 5. From those which are usually covered, occasionally single
issues are left out.
Report series (preprints) are practically notcovered, except Jadernye Konstanty (YK).
NDS scans more USSR
publications than CJD (e.g. complete coverage of JINR-reports, Dubna).
We received no CINDA entries for 82KIEV.
The incomplete CINDA coverage by CJD is illustrated by the following
table:

Examples: For 80KIEV CJD had submitted less than 50% of the entries
found by NDS. Often "MANY" entries by CJD should not be coded as MANY
but under all isotopes listed. (Thus the higher number of NDS entries is
not only due to incomplete coverage.) See also table on last page.

ad 2)
For the archival issue CINDA-A, CJD had already transmitted
CINDA entries with block numbers (and serial numbers where required).
This has been abandonned in the meantime. For NDS it is often difficult
to identify blocks and to assign block-numbers, in particular for the
EXFOR index lines. Often the references quoted must be consulted again
for checking. Due to the shortage of manpower at NDS, this cannot be
continued, and we must find procedures by which the blocking can be done
at CJD, with minimum work at NDS.
These procedures will require sending to CJD more frequently thearea-4 CINDA file. But also, improved CINDA work at CJD will be required
to mark references as superseded or with the "no-book flag" asappropriate.

ad 3)
The correctness of the entries submitted by CJD must be improved
considerably. Examples:
The comments "SIG(NEUT-E)" or "ANG ANISOTROPY" were found in entries
with the quantities DEL/DIN or NFY which, obviously, cannot becorrect.
Suchinconsistencies
areeasilydetected,butthecorrection is time-consuming and requires consultation of thereferences. Note, that this example is not a single case.
-

Sometimes not all CINDA relevant reactions in an article are indexed.

- 81 -

Energy ranges often correspond to those given in the abstract which
may be different from the actual measurement (in most cases:
resonanceparameters,orseveralquantities
withdifferent
thresholds).
"MANY" entries are made for evaluations covering several nuclides.
CINDA relevant articles are missed, although other articles from thesame issue are covered.
-Comments are very short.
EXFOR index lines have blank energy fields, no ref dates andsometimes no comments. When I consulted the corresponding TRANS
tapes in order to complete the information, I further found that
A few EXFOR entries were not indexed for CINDA.

It seems that the defaults outlined above could be solved by the"double check" procedure employed at NDS particularly for EXFOR. Thismeans in detail that the CINDA entries prepared by one physicist shouldbe "double checked" by a second physicist at CJD.
Similarly, thecoverage control requires double-checking.
A problem related to all 3 items above is that in Soviet publications
frequently the lab is not given. When I index such area 4 publications,this means some detective work to trace down the correct lab. I believethat CJD should be able to enter the correct lab also in those cases
where it is not given in the publication.
