1095241 | 095_Am_241 | ENDF/B-VII.0 | P.Young [10/26/06] Modified MF=13,MT=3 continuum x/s following the prescription by H.Trellue and R.Little to correct problems in running MCNPX. Also regridded MF=13,MT=3 summed x/s, added MF=15,MT=3 dummy spectrum at 1.e-5 eV, and corrected gridding problems & inconsistencies between MF=3 and MF=9. |
ENDF/B-VI Rev. 2 | MF=3 Neutron Cross Sections MT=2 Adjusted to that cross sections sum to total. MT=16,17 GNASH calclautions, and the parameters were adjusted to reproduce the experiemtal data of Lougheed [Lo01], Filatenkov [Fi99], and LANL C-INC data. MT=18 The SOK code was used for evaluating the fission cross section from 6 to 17 MeV. GNASH calculation was adopted at high energies. MT=102 Hauser-Feshbach statistical model calculations, and renormalized to the experimental data of Gayther [Ga77], and Wisshak [Wi80]. MF=9 Multiplicities for production of radioactive elements MT=102 Re-evaluated based on the GNASH calculation and experimental data of Shinohara [Si97], and LANL C-INC. Fi99 A.A.
