78-Pt-196 EVAL-Jun15 K.Shibata (JAEA) JNST 54,147 (2017) DIST-DEC21 20180720 ----JENDL-5 MATERIAL 7843 -----INCIDENT NEUTRON DATA ------ENDF-6 FORMAT History 2015-06 Evaluated with CCONE code by K.Shibata (JAEA) /1/ 2018-07 Activation cross sections and MF=3,6/MT=600-849 added. 2020-10 Energies of discrete primary photons were corrected. MF= 1 General information MT=451 Descriptive data and directory MF= 2 Resonance parameters MT=151 Resolved and unresolved resonance parameters Resolved resonance region: 1.0e-5 eV - 1.8 keV Parameters were taken from the compilation of Mughabghab /2/. The neutron width at -243 eV was adjusted so as to reproduce the thermal capture cross section measured by Farina Arbocco et al./3/ Unresolved resonance region: 1.8 keV - 100 keV The parameters were obtained by fitting to the total and caputure cross sections calculated from CCONE /4/. The unresolved parameters should be used only for self-shielding calculation.
