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.

4. METHOD OF SOLUTION

The library has been generated by the AMPX-II modules NPTXS, XLACS and XLACS-2.

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.
