Note:The IAEA-NDS-reports should not be considered as formal publications. When a nuclear
data library is sent out by the IAEA Nuclear Data Section, it will be accompanied by an
IAEA-NDS-report which should give the data user all necessary documentation on contents,
format and origin of the data library.
IAEA-NDS-reports are updated whenever there is additional information of relevance to theusers of the data library.
For citations care should be taken that credit is given to the author of the data library and/or
to the data center which issued the data library. The editor of the IAEA-NDS-report is usually
not the author of the data library.
Neither the originator of the data libraries nor the IAEA assume any liability for theircorrectness or for any damages resulting from their use.

INTRODUCTION
The nuclear reaction data dictionaries contain the keywords and codes used by the Nuclear
Reaction Data Center Network (NRDC) in the exchange and dissemination of nuclear
reaction data and the associated bibliographic references. These dictionaries are central to the
nuclear reaction database system with respect to compilation, checking, retrieval, plotting,conversion to computational formats, and most other applications. Therefore, their careful
maintenance and the timely distribution of updates are essential tasks within the NRDC
network.
The dictionaries are maintained by the Nuclear Data Section (NDS). All dictionary updates 1
are made on the NDS Master Archive, and are transmitted periodically to the other Nuclear
Reaction Data Centers in one or more of the following forms: the complete Master Archive
file, an EXFOR Dictionary transmission file, or a DANIEL backup file.
The formats of these files are described in this Manual. For certain applications (e.g. the
EXFOR check program), additional, specially formatted versions of the dictionaries may bein use. These are produced automatically by special software from the standard dictionaries
mentioned above, and are not described here.
This manual describes the format and contents of the dictionaries, as needed by compilers
and software developers. As the dictionaries are maintained and updated only at NDS, thedetailed updating procedures are not described here, but in an internal NDS document.
Also included in this manual is more detailed information for specific dictionaries of special
interest.
The EXFOR dictionaries contain explanations for all keywords and codes used in CINDA
and EXFOR. A dictionary identification number ranging between 1 and 999 is assigned toeach dictionary.

Contents of the different dictionary forms

1



The Archive dictionaries are the source of the contents of all forms of the dictionaries.
They contain all coded information, code expansions, and flags, as well as free text
explanations for compilers.



The EXFOR transmission dictionaries (in a format similar to an EXFOR TRANS file)contain the codes, their expansions, and the free text explanations, but not all flags
needed for the checking and other programs.



The DANIEL backup dictionaries contain all codes and flags needed for programs, andmost of the code expansions, but no free text explanations.

See NRDC Protocol for dictionary updating procedures.

EXFOR/CINDA Dictionary Manual

These different dictionary formats developed historically and were modified several times.
Therefore, the numbers of some dictionaries changed, and some old versions of dictionaries aresuperseded (no longer used by standard EXFOR software and no longer updated), but are still
kept in the system for some more time for backwards compatibility. See the Table ofDictionaries further below for a summary.
Dictionary distribution
The dictionaries are distributed in one or more of the following ways:- in the NDS open area, subdirectory DICTS- through the EXFOR backup web page http://www-nds.iaea.org/exfor-master/backup/
These distributions may also contain the latest version of the EXFOR check program CHEX
with the correspondingly formatted dictionaries (ZVV). A program to generate these ZVV
dictionaries from the DANIEL backup file for various computer platforms is also included inthis distribution.

Chapter 1
DICTIONARIES GENERAL
1.1 Dictionary Contents
Each dictionary contains the following items of information:
1. Keyword or code: There are four keyword dictionaries; the remaining dictionaries define
codes used within the BIB section under specific information-identifier keywords (see the‘Table of Dictionaries’ below).
The keyword dictionaries are:Dict. 1
Dict. 2
Dict. 24
Dict. 25
2.

System identifiers (see EXFOR Systems Manual Chapter 2)
Information identifiers (see EXFOR Systems Manual Chapter 3)
Data headings Used in COMMON and DATA sections (see EXFOR
Data units
Systems Manual Chapter 4)

Expanded forms 2 are provided in certain dictionaries (see Table of Dictionaries), and are
self-explanatory.

3. Free Text explanation of the keyword or code.
4. Other coded information is included for many of the dictionaries (e.g., the country oforigin for journal codes, certain flags for checking purposes in the case of data-heading
keywords). For details see the dictionaries themselves, and the ‘Table of Dictionaries’
below.
Status of dictionary keywords or codes
The validity of a dictionary keyword or code may have expired or be restricted. This isindicated by an Obsolete flag (OBS or O) or an Extinct flag (EXT or X):
An Obsolete flag indicates that the keyword or code is not permitted on newtransmissions, although it may still exist in entries that were transmitted previously. An
explanation as to why the code is obsolete and which code (if any) replaces it may be
given in free text. Obsolete codes remain in the dictionary until all cooperating centers
have removed them from their data files.
An Extinct flag indicates that the given code designates an extinct institute, journal, or
report series. The code is still valid on transmissions, but will occur only in entries of old
data.
2

The expanded form may be used to replace the code in an output format, so that the EXFOR user may read theentries without having to consult the dictionaries to find the meaning of the codes.

1.3 Additional Information on Specific Dictionaries
Remember that references to free text explanations refer to the Archive and TRANS
dictionaries only.
Dictionary 3. Institute. The 7-character code ABBBCCC is constructed as follows:= service-area code, 1, 2, 3, or 4 as defined among neutron data centers (see EXFOR
Systems Manual, page 1.4).
BBB = country code
CCC = lab code (may be less than 3 characters, left adjusted)A

The 3-character institute codes include all laboratory, university, institute, agency andcommission codes in use in the CINDA/EXFOR system, and must be unique.
Where the code identifies only a country, the information in the country-code field (columns2-4) is repeated in the lab-code field (columns 5-7), as for example: 1CANCAN (Canada).
For this reason, a lab code may not be identical to a country code.
For obsolete and extinct codes, the code that replaces it, if any, is given (in free text) in allcases. The dictionary is sorted by the code, thus grouping together the institutes for each area
and country.
Dictionary 5. Journals. The actual journal code is restricted to 4 characters or less. Wherejournals are subdivided into parts, the part is included in the dictionary with the journal code,and separated from it by a slash; the complete code is restricted to 6 characters, as forexample:ND/A = Nuclear Data, Part A.
The expanded form follows the commonly adopted style for journal titles. However, someabbreviations have been expanded for clarity.
Dictionary 6. Reports 8 . The codes are 11 characters or less in length. Each code in the
dictionary consists of the alphanumeric character string that precedes the actual report
number. The final character of the codes given in the dictionary is always a hyphen (-),
except in a few cases where the report codes are 11 characters; 12th character (not given in
the dictionary) is a hyphen. Since the code and the number may both contain hyphens, theseparator is defined as the first hyphen that is followed by a digit or an opening parenthesis,
for example:

8Some older CINDA lines may use old CINDA codes.

separator
AERE-C/R- 159-MS
CodenumberAnnual progress reports which do not have a report number given are assigned an EXFOR
report code A-, followed by the 3-digit institute code; when coded, the code is followed by
the year for which the report is given.
Examples:A-ARK-84 or A-COL-1999

Dictionary 7. Conferences. Codes are up to 10 characters.
Conference codes are composed of the year of the conference given in the first 2 digits (up to1999) or the first 4 digits (from the year 2000) of the code, followed by the place of theconference, which may have up to 6 characters.
Examples: 66PARIS
82ANTWER
2007NICE
Two conferences at the same place in the same year may be distinguished as shown in thefollowing examples.
66ANL and 66ARGONNE
80BNL and 80BNL-2
69WIEN and 69VIENNA
Two expanded forms may be given: a short expansion, restricted in length to the explanation
field of one record, which may be followed by a long expansion, starting on a new record andextending over more than one record. In Archive and DANIEL backup dictionaries, the short
expansion is not enclosed in parentheses.
See also LEXFOR Reference.
Dictionary 16. Status codes.
The dictionary contains a subaccession number flag, as follows.
R - code must be followed by subaccession #S - code may be followed by subaccession #Dictionary 24. Data Headings. The data headings are used in the COMMON and DATA
sections to define the contents of data fields. No expanded form of the codes is given.
Codes should be unique within Dictionary 24 and 25, i.e., a data heading may not be identicalto any data unit.

EXFOR/CINDA Dictionary Manual

Many headings are identified by a family flag, which used for checking purposes and defines
the category and the family (or independent variable type) within each category, according to
the scheme in the following table.

An additional, more detailed classification scheme for headings is used in the Archive and
DANIEL backup dictionaries; see Chapters 2 and 5.2 for details.
Dictionary 25. Data Units. The data units are entered in the COMMON and DATA section
below the data heading to define the units for the contents of each field.
Codes are unique within Dictionary 24 and 25, i.e., a data unit may not be identical to any
data heading.
Each unit is assigned a dimension code, which provides a cross-link with Dictionary 24 and
236 (Quantity Dictionary), where the dimension code is also given (see page 10). Thisfacilitates computerized crosschecks for consistency of quantities and units in a table.
Each unit is also assigned a conversion factor, which is given as a floating-point number andmay be used for transforming units with the same dimension to standard units, for example:
9

Associated quantities are those data heading keywords which contain the characters ERR or RSL
Except LVL-INI and LVL-FIN.
11
In certain cases, these may act as an independent variable with the exception of Flag.

to electron-volts (eV);to degrees;
to seconds (s);to meters (m);to barns (b).

In order to standardize the data unit codes, the following will be used:
PRT for outgoing particle, i.e., for particle given in REACTION SF3 or SF7.
PRD for reaction product, i.e., REACTION SF4.
INC for incident projectile, i.e., REACTION SF2.
REAC for reaction, in general, REACTION SF2-SF3, with the exception that FIS will be
used for fission.
PC for percent or per 100 particles.
Examples: PRD/FIS or PRT/REAC
Dictionary 33. Particles. All particles used in used in the BIB section are included in this
dictionary, which contains a four-character “allowed use” flag as follows.
D – used in BIB keyword other than REACTION
1st characternd
2 character2 – used in REACTION SF2
3rd character3 – used in REACTION SF3th
4 character
7 – used in REACTION SF7
Dictionary 34. Modifiers (REACTION). An expanded form is only given for thosegeneral-quantity modifiers (at the beginning of the transmission dictionary) that may be
included in the REACTION code, but are not included in the quantity codes given in Dictionary
36.
Dictionary 207. Books.
Book codes give a concise short title of the book, or the family name of the first author.
Examples:

ABAGJAN NEJTRONFIZ -Group Constants for Nuclear Reactor Calculations, Abagjan,
et al., 1964
Neytronnaya Fizika, P.Krupchitskiy, 1961

Two expanded forms may be given: a short expansion, restricted in length to the explanation
field of one record, which may be followed by a long expansion, starting on a new record andextending over more than one record. In Archive and DANIEL backup dictionaries, the short
expansion is not enclosed in parentheses.
Dictionary 209. Chemical Compounds. The general compound code CMP can be combinedwith any element in the form (Z-S-CMP) without entry in this dictionary, which only lists
special cases. The actual compound codes (e.g., OXI for oxide) are restricted to threecharacters. The codes are sorted by atomic number of the principal element in the compound.
See also LEXFOR Chemical Compounds.

9

EXFOR/CINDA Dictionary Manual

Dictionary 227. Nuclides and natural isotopic mixtures.
The nuclide code has the format Z-S-A(-M)
where:
Z=
the charge number, up to 3 digits, no leading zeros;S=the element symbol; 1 or 2 characters;A=
the mass number; up to 3 digits, no leading zeros; a single zero denotes
natural isotopic composition.
The code is right adjusted on Z, i.e., the Z ends in the 3rd position, and continuing with noblanks in the code. All metastable states are labeled as –M.
The data associated with a nucleus are taken from the Nuclear Wallet Cards and the AudiWapstra Mass Tables. All nuclides given in the Nuclear Wallet Cards are included.
Dictionary 236. Quantities. The quantity code is composed of the codes for the REACTION
subfields 5 to 8.
A short expanded form (not enclosed in parentheses) is given as a short definition of thequantity. A longer expansion (in parentheses) may follow on the comment lines.
Resonance parameters are flagged with a “.” in column 52 (immediately preceding the short
expansion).
All meaningful combinations of the codes that are in use are included in this dictionary, withthe following two exceptions:- These quantity codes do not include the general-quantity modifiers from Dictionary 34(see remarks on this dictionary).
- The Particle Designator Field may contain a wildcard in place of an explicit code for theparticle considered:
In order to keep the size of the dictionary to a minimum, specific particles are not always
included in the particle designator field (REACTION SF7). Instead, this field may contain acode indicating that a particle designator (or designators) is legal for this quantity.
**F

All codes from Dictionary 33 with flag ‘7’, and nuclides from Dictionary 227
except those with use flag ‘Z’ ;Any fission fragment particle code is allowed, i.e., FF, LF, HF.

If the particle designator is blank, only a blank field is allowed for that quantity 12 .
If more than one particle designator must be given (e.g., for correlations), the codes are
given for each particle, separated by slashes.
Examples: PAR,TTY,A
DA/CRL,P/D,AKE,*F,DA/DA,*/*

12

This means that there must be a separate dictionary entry for the quantity with codes in SF7.

10

EXFOR/CINDA Dictionary Manual

The reaction type code provides a cross-link to Dictionary 213 through which the necessary
independent variables for each quantity (such as angles and secondary energies) are defined.
This facilitates computerized checks of whether quantities and variables given in a table areconsistent.
The dimension code provides a cross-link to Dictionary 25 (Data Units), where the dimension
code is also given (see page 8). This facilitates computerized checks of whether quantities
and units given in a table are consistent.

DANIEL BACKUP DICTIONARIESThe DANIEL Backup Dictionaries are a version of the dictionaries containing only the
information needed for interfacing with computer programs, i.e. a subset of the information
contained in the Archive dictionaries. They contain all codes and flags needed for computer
programs, but no comments and free text explanations. They combine all dictionary informationin one ASCII (text) file which can be used to generate (load) a dictionary database specific to acertain application (e.g. EXFOR check program) and/or a certain software platform.
The DANIEL Backup (File name: DAN_BACK_NEW.9nnn or DAN_BACK_NEW.ALL)
consists of an index part (similar to the index file of the Archive dictionaries) and the actual
dictionary records.

Status Codes
The status codes used are the same as in the Archive dictionaries, see Chapter 2.
Redefining the data baseSince the format of the records for each dictionary is contained in the dictionary index, fields
may be re-defined, added, and/or eliminated without changing the programs. New dictionaries
may be added and old ones eliminated by updating the index records.
Normally, a dictionary will be added through creating a new file for the Archive dictionaries.
Then the archive index (DICT_ARC.TOP) must be updated accordingly, reflecting the contentsof the new dictionary. Then an updated DANIEL Backup file can be generated by theappropriate software run at NDS (program MAKE_BACK).
Dictionary Contents
The contents of the DANIEL backup dictionaries are very similar to the Archive dictionaries,
therefore below only the differences are mentioned:- The DANIEL backup dictionaries do NOT include any of the COMMENT records of theArchive dictionaries- Dictionary 1 (System Identifiers): Field 2 (Expansion) is NOT included- Dictionary 25 (Data Units): Field 4 (Sorting code) is NOT included
See the description of the Archive dictionaries for the detailed contents.

Chapter 4
EXFOR TRANSMISSION DICTIONARIES

4.1 General Information and Format
The dictionary transmission files have much the same format as an EXFOR exchange file.
Both the structure of the dictionary transmission files and the format of the individual
dictionaries are described in this chapter. More detailed information for specific dictionaries
of special interest is also included.
EXFOR Transmission Dictionaries (File name: TRANS.9nnn)
The first record on the dictionary transmission is a TRANS record; the last record is an
ENDTRANS record (compare EXFOR Exchange Formats Manual, Chapter 2 on System
Identifiers). The content of N1 and N2 is as follows.
• For the TRANS record, N1 and N2 are the same as for a regular EXFOR transmission file.
"9" is used as the center identification character, although in column 67 the center
identification "3" is used (as throughout the file).
• For the ENDTRANS record, N1 contains the number of dictionaries transmitted and N2 isblank.
Dictionary Format
The format of the transmitted dictionaries is generally similar to that of the BIB section in
EXFOR entries.
Keyword or code: the keyword or code to be defined is given, left adjusted, in the first field,
starting in column 1. The field is usually contained in columns 1-11, but may be longer forcodes related to quantities. The keywords have a maximum length of 10 characters; somecodes are restricted to a length of 3 or 5 characters (see Chapter 1, Table of Dictionaries).
Explanation: The explanation field usually starts in column 12 (in column 23, in the case ofquantity codes) and usually (but with some exceptions) ends in column 66 of the first record.
Expanded forms are enclosed in parentheses; the opening parenthesis is given in the firstcolumn of the explanation field. The expanded form is normally restricted to the length ofthe explanation field of one record, but, for certain dictionaries (see pages 1.2–1.3), theexpanded form may continue within the explanation field onto following records.

29

EXFOR/CINDA Dictionary Manual

Free text may immediately follow the closing parenthesis of the expanded form or, if no
expanded form is given, begin in the first column of the explanation field. It may continue
within the explanation field, onto any number of records. The free text may include
parentheses, but a left parenthesis that is part of the free text must not be entered in the firstcolumn of the explanation field (signaling the presence of an expanded form).
Record identification: The record identification (columns 67-79) of a dictionary record
contains "30000" in columns 67-71, the dictionary identification number in columns 72-74
with leading zero(s), and the record sequence number with leading zeros in columns 75-79.
Flag: Column 80 is used
1. to flag certain validity conditions for the code given on the same record. These flags
remain permanently attached to the respective codes or keywords. For an explanationof the Obsolete flag (O) and the Extinct flag (X) see Chapter 1.
2. as an indication that the record was altered since the last dictionary transmission (i.e.,
added, deleted, corrected). See EXFOR Exchange Formats Manual, Chapter 8, foruse of alteration flags.
The following two system-identifier records identify the beginning and the end of eachdictionary (see EXFOR Exchange Formats Manual, Chapter 2, for record format).
1.

DICTION is the first record of each dictionary.

N1 - Dictionary identification number (see above).
N2 - Date of last change (year, month, day - YYYYMMDD).
Columns 34-66 describe the contents of the dictionary in free text.
The record identification (columns 67-79) contains "30000" in columns 67-71, thedictionary number in columns 72-74, and the record sequence number "00001" incolumns 75-79.
2.

ENDDICTION is the last record of each dictionary.

N1 - Number of records in the dictionary, excluding the DICTION and ENDDICTION records.
N2 - Presently unused (may be blank or zero)
The record identification is the same as in the DICTION record, except that the record
sequence number is "99999".
The order of entries in each dictionary has been chosen for ease of use by compilers. It is theprerogative of each center to rearrange the dictionary for their own purposes if they wish,e.g., for optimum computer use.

4.2 Additional Information on Specific Dictionaries
Apart from the general differences explained in the Introduction, the contents of the EXFOR
transmission dictionaries is similar to the Archive dictionaries; they contain the codes, code
explanations, expanded forms and additional free text, but not all the flags included in theArchive and DANIEL backup dictionaries. This section deals only with additional
information concerning such differences, e.g. with flags which are included but are in adifferent position on the dictionary record.
Dictionary 4. Type of reference. This dictionary is in the standard format except thatcolumns 56-61 of the explanation field are reserved for the term "DICT n" pointing to thedictionary number n which contains the reference codes to be used with the given reference
type. Columns 56-61 are blank when no dictionary applies.
Dictionary 5. Journals.
The area code and country code (country of publication) are in columns 63 to 66.
Dictionary 6. Reports.
The 7-character institute code (as in Dictionary 3) of the institute at which the report wasissued is given in columns 60 to 66.
The dictionary is sorted on the institute code and, within the institute code, by report code.
This sorting is different from the Archive and DANIEL backup dictionary which are sorted
by report code.
Dictionary 7. Conferences.
The short expanded form is enclosed in parentheses (this is different from the Archive
dictionary). The long expanded form is also given.
Dictionary 19. Incident Source.
This dictionary is in the standard format except that column 66 of the explanation field isreserved for a field delimiter which indicates that another code is expected following the
given code, separated by the delimiter.
Dictionary 24. Data Headings.
The family flag is given in Column 66.

Columns 1 - 18 quantity code (or 1-44, see below)
19 - 21 dimension code22
resonance parameter flag
23 - 66 expanded form and free text.
1. Resonance parameters are flagged with a "." in column 22.
2. The short expanded form is enclosed in parentheses (different from the Archive
dictionary). The long expanded form is also given.
3. If the quantity code length is >18 characters, the code is continued on the same record andfollowed by blanks and "9" in column 66. The dimension code and the expansion follow
on the next record in their assigned fields. Maximum code length = 44 characters.

Chapter 5
RELATIONS BETWEEN QUANTITIES, HEADINGS AND UNITS

Embedded in the dictionaries is a variety of flags establishing connections and hierarchicalrelations between various dictionaries and the codes they contain, in particular quantities andthe appropriate headings and units. These relations are essential for automatic checking of
EXFOR input, conversion to computational formats and data processing, data plotting,comparison of experimental with evaluated data, etc. Furthermore, understanding of these
relations is necessary for correct and consistent maintenance of the dictionary database,particularly when adding new codes.
These relations have mainly existed implicitly in the dictionary files, and were notconveniently summarized. This chapter attempts to give a concise summary of the mostimportant of these relations; strictly speaking, it does not contain additional information,
since – in principle – all of this chapter can be extracted from the dictionary files themselves
and the descriptions of the previous chapters.

5.1 Hierarchy of Quantities
EXFOR quantity - Reaction Type - CINDA quantity - Web quantity
The EXFOR quantity dictionary (Dictionary 236) contains presently about 770 quantities.
This is not only inconvenient but also confusing for many users, especially when retrieving
data. Therefore, there have always been attempts to group these quantities into categories tomake retrievals easier. At the same time, there were already more general “bulk” quantities;
particularly, the quantities for the CINDA bibliography which has always been closely
related to EXFOR; furthermore, for purposes of easy web retrievals, another quantity
grouping system was developed. However, even though there were only around 45 CINDA
quantities, the situation remained complicated because of the occurrence of numerous manyto-many relations (some of the 770 EXFOR quantities corresponded to more than one of the
45 CINDA quantities; and most CINDA quantities correspond to many EXFOR quantities).
Within the EXFOR system, the “Reaction Type” flag constitutes another grouping ofquantities reflecting not only the type of physical quantity but also serving as a link to therelated independent variables (such as angles and secondary energies).
Since this large variety of quantity categories was found to exist, an attempt was made to
streamline the situation when the “new CINDA” quantities were introduced; no many-tomany relations exist any more. A simple hierarchy of quantities has been established:

35

EXFOR/CINDA Dictionary Manual

EXFOR quantity → Reaction Type →New CINDA quantity → Web quantity(~770)(~117)(~42)(~25)(Dict. 236)
(Dict. 213)
(Dict. 45)(Dict. 113)
i.e., every EXFOR quantity belongs to only one Reaction Type; every Reaction Type belongs
to only one CINDA quantity; and every CINDA quantity belongs to only one Web quantity.
This hierarchy makes the situation much easier to understand; also, software developers
and/or users can decide on which level of detail they want to base their retrievals or retrieval
software. At the same time, it requires additional care in the dictionary maintenance to keep
the hierarchy with its structure intact; in particular when adding new EXFOR quantities, e.g.
a new type of differential data, it has to be checked whether an existing Reaction Type can beused (which links to all necessary independent variables), or whether a new Reaction Typecode is needed as well.
To make these hierarchies visible, two correspondence lists are given below:Correspondence Web quantity – CINDA quantities
Correspondence CINDA quantity – Reaction Types(To see the correspondence Reaction Type – EXFOR quantities, one could sort Dictionary
236 by Reaction Type. This is omitted here for space reasons.)

5.2 Dictionary 24 classes
As mentioned in Chapter 1, the data headings collected in Dictionary 24 are categorized in
two ways: the Family Flags as described in Chapter 1, and two numerical “Data type” flags
as described in Chapter 2. (The EXFOR Transmission dictionaries contain only the family
flags.) The following table combines the Data type flags with the headings for which they areused, and with the Family flags. It should also be noted that the Archive and DANIEL backup
dictionary 24 contain additional flags (“plotting flags”) which are not included in the tablebelow; see Chapter 2 for more details.

5.3 Dictionary and Checking Logic around Quantities, Headings and Units
When updating the relevant dictionaries, or when compilers propose new codes for quantities,
headings or units, it is useful to visualize the relations between the relevant dictionaries andthose fields which occur in more than one of them. These relations are shown on the figure
below.
