                 OUTPUT FORMAT OF DATA_FILE.CRP
         
===========================================================================


The format of the DATA_FILE.CRP file is essentially that of the MF=3
file of ENDF-5 format with the following deviations (the
resulting format is usually referred to as the FENDL/A or EAF format):

1. Two comment lines are used stating the origin of data, revisions and
information about renormalizations.

2. The material number MAT consists of Z and two last digits
of A.

3. The identifier LFS is used to indicate the
(isomeric) states of the final nucleus. Here the convention was adopted 
that LFS =99 means total production cross-section; LFS = i means production
of ground state (i = 0), m1 (i = 1) and m2 (i = 2), respectively. The 
reaction nomenclature is that of ENDF format, except that reaction numbers 
leading to metastable states have been increased by 300 or 600 (for m1 and m2, 
respectively). The cross sections for one material number are ordered according 
to increasing MT numbers, except that cross sections leading to metastable 
states follow immediately after the cross section leading to the ground state.

   The reaction to the ground state is given first, followed by reactions to 
the metastable states, (if any).
