Identification number
The individual requests then follow in order of increasing
identification number. This number appears on the first
line of each request at the far left and is underlined. The
number assigned is unique and remains associated with a
request. When a request is withdrawn, this number is not
assigned to another request. The first two digits of the
identification number are the last two digits of the year
in which the request was originated. The third digit represents
the responsible neutron data center (1-NNCSC,
2-NDCC, 3-NDS, 4-CJD) and the final three digits are a sequence
number. The neutron data centers are responsible for
assigning the identification number.
Energy
The next two entries on the first line of each request
give the range of energy of the incident particle over which
data are desired. The energy unit is given after each number.
Because no lower case is used, we have adopted the symbol,
MV, for milli-electron volts, thus preventing confusion with
MEV for million electron volts.
If an energy appears in the first field with the second
field blank, then the requested information is required at
only a single energy. In the case of a resonance integral,
the single entry gives the lower energy limit for the integral.
A lone entry in the second energy field with the first field
blank indicates that measurement is desired for energies up to
the specified value. This format appears most frequently for
threshold reactions. No alphabetic energies are allowed. Thus
thermal is given as 25.3 MV. All spectrum averages and nonstandard
energy specifications must be explained in the requestors
comments.
