INTRODUCTION

This manual is intended as a guide to users of nuclear reaction data compiled in the EXFOR
format, and is not intended as a complete guide to the EXFOR System.1
EXFOR is the exchange format designed to allow transmission of nuclear reaction data between
the Nuclear Reaction Data Centers. 2 In addition to storing the data and its' bibliographic
information, experimental information is also compiled. The status (e.g., the source of the data)and history (e.g., date of last update) of the data set is also included.
EXFOR is designed for flexibility in order to meet the diverse needs of the nuclear reaction data
centers. It was originally conceived for the exchange of neutron data and was developed
through discussions among personnel from centers situated in Saclay, Vienna, Livermore andBrookhaven. It was accepted as the official exchange format of the neutron data centers at
Saclay, Vienna, Brookhaven and Obninsk, at a meeting held in November 1969.3 As a result of
two meetings held in 1975 and 19764 and attended by several charged-particle data centers, theformat was further developed and adapted to cover all nuclear reaction data.
The exchange format should not be confused with a center-to-user format. Although users may
obtain data from the centers in the EXFOR format, other center-to-user formats have beendeveloped to meet the needs of the users within each center's own sphere of responsibility.
The EXFOR format, as outlined, allows a large variety of numerical data tables with explanatory
and bibliographic information to be transmitted in a format:• that is machine-readable (for checking and indicating possible errors);• that can be read by personnel (for passing judgement on and correcting errors).
The data presently included in the EXFOR exchange file include:• a "complete" compilation of experimental neutron-induced reaction data,• a selected compilation of charged-particle-induced reaction data,• a selected compilation of photon-induced reaction data.

EXFOR Basics
EXCHANGE FILE FORMAT
An exchange file contains a number of entries (works). Each entry is divided into a number ofsubentries (data sets). Each entry is assigned an accession number; each subentry is assigned asubaccession number (the accession number plus a subentry number). The subaccession
numbers are associated with a data table throughout the life of the EXFOR system.
The subentries are further divided into:• bibliographic, descriptive and bookkeeping information (hereafter called BIB information),• common data that applies to all data throughout the subentry , and• a data table.
The file may, therefore, be considered to be of the following form:
File

Entry

Subentry
Bibliographic
Information
Common
Data
Data
Table

In order to avoid repetition of information that is common to all subentries within an entry or
to all lines within a subentry, information may be associated with an entire entry or with anentire subentry. To accomplish this, the first subentry of each work contains only informationthat applies to all other subentries. Within each subentry, the information common to alllines of the table precedes the table. Two levels of hierarchy are thereby established:
Entry

EXFOR Basics

EXFOR Records
EXFOR Exchange files consist of 80 character ASCII records. The format of columns 1-66
varies according to the record type as outlined in the following chapters. Columns 67-79 isused to uniquely identify a record within the file. The records on the file are in ascendingorder according to the record identification. Column 80 is reserved for an alteration flag.
Record identification. The record identification is divided into three fields: the accession
number (entry), subaccession number (subentry), and record number within the subentry. The
format of these fields is as follows.
Columns 67-71 Center-assigned accession number
72-74 Subaccession number
75-79 Sequence number
Alteration flag (column 80). The last column of each record contains the alteration flag,
which is used to indicate that a record and/or following records has been altered (i.e., added,
deleted or modified) since the work was last transmitted. The flag field will normally containa blank to indicate an unaltered record.

POINTERS
Different pieces of EXFOR information may be linked together by pointers. A pointer is anumeric or alphabetic character (1,2...9,A,B,...Z) placed in the eleventh column of theinformation-identifier keyword field in the BIB section and in the field headings in the
COMMON or DATA section.
Pointers may link, for example,• one of several reactions with its data field;• one of several reactions with a specific piece of information in the BIB section (e.g.,
ANALYSIS), and/or with a value in the COMMON section, and/or with a field in the
DATA section;• a value in the COMMON section with any field in the DATA section.
In general, a pointer is valid for only one subentry. A pointer used in the first subentry
applies to all subentries and has a unique meaning throughout the entire entry.

10

EXFOR Basics
BIB SECTION
The BIB section contains the bibliographic information (e.g., reference, authors), descriptive
information (e.g., neutron source, method, facility), and administrative information (e.g.,history) associated with the data presented. It is identified on an exchange file as that
information between the system identifiers BIB and ENDBIB.
A BIB record consists of three parts:
columns 1-11: information-identifier keyword field,
columns 12-66: information field, which may contain coded information and/or freetext,
columns 67-80: record identification and alteration flag fields.
BIB information for a given data set consists of the information contained in the BIB sectionof its subentry together with the BIB information in subentry 001. That is, information codedin subentry 001 applies to all other subentries in the same entry. A specific informationidentifier keyword may be included in either subentry or both.
Information-identifier keywords
The information-identifier keyword is used to define the significance of the information given
in columns 12-66. The keyword is left adjusted to begin in column 1, and does not exceed alength of 10 characters (column 11 is either blank, or contains a pointer, see Chapter 5).
These keywords may, in general, appear in any order within the BIB section, however, an
information-identifier keyword is not repeated within any one BIB section. If pointers arepresent, they appear on the first record of the information to which they are attached and are
not repeated on continuation records. A pointer is assumed to refer to all BIB information
until either another pointer or a new keyword is encountered. As this implies, pointerindependent information for each keyword appears first.
Coded (machine-retrievable) information
Coded information may be used:• to define the actual BIB information,• as a link to the COMMON and DATA section,• to enter associated numerical data.
Coded information is enclosed in parentheses and left adjusted so that the opening
parenthesis appears in column 12. Several pieces of coded information may be associatedwith a given information-identifier keyword.
Codes for use with a specific keyword are found in the relevant dictionary. However, forsome keywords, the code string may include retrievable information other than a code fromone of the dictionaries.

11

EXFOR Basics
In general, codes given in the dictionaries may be used singly or in conjunction with one ormore codes from the same dictionary. Two options exist if more than one code is used:a) two or more codes within the same set of parenthesis, separated by a comma;
Example: (SOLST,NAICR)b) each code on a separate record, enclosed in it's own set of parenthesis starting in column
12, followed by free text.
Example: (SOLST) free text
(NAICR) free text
For some cases, the information may be continued onto successive records. Information oncontinuation records does not begin before column 12 (columns 1-10 are blank and column
11 is blank or contains a pointer).
Note that some information-identifier keywords have no coded information associated withthem and that, for many keywords that may have coded information associated with them, it
need not always be present.
Free text
Free text may be entered in columns 12-66 under each of the information-identifier keywords
in the BIB section. The text follows any coded information on the record or may begin on a
separate record; it may be continued onto any number of records.
The language of the free text is English.
Coding of nuclides and compounds.
Nuclides appear in the coding of many keywords. The general code format is Z-S-A-X,
where:
Z is the charge number; up to 3 digits, no leading zeros
S is the element symbol; 1 or 2 characters (Dictionary 8)
A is the mass number; up to 3 digits, no leading zeroes. A single zero denotes natural
isotopic composition.
X is an isomer code denoting the isomeric state; this subfield is not used if there are no
known isomeric states.
X may have the following values:
G for ground state (of a nucleus which has a metastable state)
M if only one metastable state is regarded
M1 for the first metastable state
M2 for the second, etc.
T for sum of all isomers (limited to use within an isomeric ratio in SF4 of thereaction string)
Examples: 92-U-235
49-IN-115-M/T

Compounds may in some cases replace the nuclide code. The general format for coding
compounds is either the specific compound code, taken from Dictionary 9, or the generalcode for a compound of the form Z-S-CMP.
Example: 26-FE-CMP

EXFOR Basics

COMMON AND DATA SECTIONS
A data table is, generally, a function of one or more independent variables, e.g.,•••

X vs. Y, e.g., energy, cross section
X, X′ and Y, e.g., energy and angle; differential cross section
X, X′ and X″ vs. Y, e.g., energy, secondary energy, angle, partial angular distribution.

When more than one representation of Y is present, the table may be X vs. Y and Y′, withassociated errors for X, Y and Y′ (e.g., X = energy, Y = absolute cross section, Y′ = relative crosssection), and possible associated information. The criteria for grouping Y with Y′ are that theyboth be derived from the same experimental information by the author of the data.
For some data, the data table does not have an independent variable X but only a function Y.
(Examples: Spontaneousν; resonance energies without resonance parameters)
Additional variables may be associated with the data, e.g., errors, standards.
The format of the common data (COMMON) and data table (DATA) sections is identical.
Each section is a table of data containing the data headings and units associated with eachfield. The difference between the common data and data table is:•

The common data contains constant parameters that apply to each line of a point datatable;•The data table contains fields of information; each field, generally, contains values as afunction of one or more independent variables (e.g., angle, angular error, cross section,
cross section error), i.e., one or more lines of data.

Each physical record may contain up to six information fields, each 11 columns wide. If
more than six fields are used, the remaining information is contained on the following records.
Therefore, a data line consists of up to three physical records. The number of fields in a dataline is restricted to 18.
Records are not packed; rather, individual point information is kept on individual records; i.e.,
if only four fields are associated with a data line, the remaining two fields are left blank, and,in the case of the data table, the information for the next line begins on the following record.
These rules also apply to the headings and units associated with each field.
The content of the COMMON and DATA sections are as follows:•

Field headings: a data heading left adjusted to the beginning of each field (columns 1, 12,
23, 34, 45, 56), plus, perhaps, a pointer placed in the last (11th) column of a field.

•

Data units: left adjusted to the beginning of each field (columns 1, 12, 23, 34, 45, 56).

•

Numerical data: FORTRAN-readable using a floating-point format, as follows.
• A decimal point is always present, even for integers.
• A decimal number without an exponent can have any position within the 11-character
field.
• No blank is allowed following a sign (+ or -).
• A plus sign may be omitted, except that of an exponent when there is no E.
13

EXFOR Basics•

In an exponential notation, the exponent is right adjusted within the 11-character field.
The mantissa may have any position.

The values are either zero or have absolute values between 1.0000E-38 and 9.999E+38.
COMMON Section
The COMMON section is identified as that information between the system identifiers
COMMON and ENDCOMMON. In the common data table, only one value is entered for a given
field, and successive fields are not integrally associated with one another.

DATA Section
The DATA section is identified as that information between the system identifiers DATA andIn the DATA table, all entries on a record are integrally associated with anindividual point. Independent variables precede dependent variables, and are monotonic untilthe value of the preceding independent variable, if any exist, changes.

ENDDATA.

Every line in a data table gives data information. This means, for example, that a blank in afield headed DATA is permitted only when another field contains the data information on thesame line, e.g., under DATA-MAX. In the same way, each independent variable occurs atleast once in each line (e.g., either under data headings E-LVL or E-LVL-MIN, E-LVL-MAX, see
example following). Supplementary information, such as resolution or standard values, is not
given on a line of a data table unless the line includes data information. Blanks are permitted
in all fields.
