The folding of cross-sections from TALYS with 3310800300030 neutron flux distributions was done by using the 3310800300031 neutron spectrum. 3310800300032 MISC-COL (MISC) Cross section before tail neutron correction 3310800300033 STATUS (TABLE) Table 3 of Applied Radiation and Isotopes 3310800300034 129 (2017) 117 3310800300035 ENDBIB 33 0 3310800300036 NOCOMMON 0 0 3310800300037 DATA 6 2 3310800300038 EN EN-ERR DATA ERR-T MISC MISC-ERR 3310800300039 MEV MEV MB MB MB MB 3310800300040 11.9 0.35 1311.72 133.98 1506.59 133.983310800300041 15.75 0.70 1484.98 182.63 2320.94 182.633310800300042 ENDDATA 4 0 3310800300043 ENDSUBENT 42 0 3310800399999 ENDENTRY 3 0 3310899999999
