Cross sections of (n, n'α) nuclear reaction on rear earth elements at 14.7 MeV neutron energy

Abstract

Cross sections of nuclear reactions 159Tb(n, n'α)155Eu, 165Ho(n, n'α)161Tb, 169Tm(n, n'α)165Ho and 176Yb(n, n'α)172Er for incident neutron energy region (8 - 20) MeV are presented. Comparison of the nuclear cross sections data with available experimental information, evaluated nuclear data and theoretical calculation results with the variation of different parameters of the theoretical models was performed. Theoretical calculations were executed with TALYS-1.2 code.
