3. DESCRIPTION OF PROGRAM OR FUNCTION
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
FORMAT: format of an AMPX-II Master Library Interface
NUMBER OF GROUPS: 219 neutron energy groups (78 thermal)
NUCLIDES: H, B, C, N, O, F, Na, Mg, Al, Si, Cl, K, Ca, Cr, Mn, Fe, Ni, Sr, Zr, Mo, Sn, Gd, Hf, U, Pu, Am
ORIGIN: JEF-1
WEIGHTING SPECTRUM: Two weighting functions have been used:
- Fission + 1/E + Maxwellian
- 1/(sigma total)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The library is given in the format of an AMPX-II Master Library Interface. Two weighting functions -
Fission+1/E+Maxwellian and 1/(sigma total) - have been used; the reference temperature of the library is 300K.
The source of microscopic data is JEF-1; 64 materials were processed with values of sigma-p.

7. UNUSUAL FEATURES OF THE PROGRAM
Many kinds of problems were encountered in processing JEF-1 (which adopts the ENDF/B-V format) with AMPX-II (especially designed to process ENDF/B-IV formatted data). For some nuclei, pre-processing tasks had to be performed in order to solve specific problems, e.g. format conversion of angular data from shortened ENDF/B-V format to explicit ENDF/B-IV. Most of the tasks could successfully be solved with the code CRECTJ5, while in some cases specific codes had to be written.
