81-Tl-205 EVAL-Jan15 K.Shibata (JAEA) DIST-DEC21 20180711 ----JENDL-5 MATERIAL 8131 -----INCIDENT NEUTRON DATA ------ENDF-6 FORMAT History 2015-01 Evaluated with CCONE code by K.Shibata (JAEA) 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 - 83.665 keV The parameters were taken from ENDF/B-VII.1, which is based on the data evaluated by Mughabghab /1/. Unresolved resonance region: 83.665 keV - 300 keV The parameters were obtained by fitting to the total and caputure cross sections calculated from CCONE /2/. The unresolved parameters should be used only for self-shielding calculation.
