Evaluation of Cross Sections for Neutron Monitor Reactions 169Tm（n,xn）168, 167, 166, 165Tm from Threshold to 100 MeV

摘要

正 The cross sections for 169Tm（n,xn）168,167,166,165Tm reactions in intermediate energy region are useful for neutron field monitor, safety design consideration and material damage research for fusion material irradiation test and the radioactivities induced in components of accelerator. The evaluation of activation cross sections of （n,2n） reaction for 169Tm has been performed below 20 MeV. In our evaluation, the identification and correction have been made to the differences and discrepancies among the existing activation cross sections from different laboratories to obtain more accurate da
