Measurement of 167Er(n,p)167Ho reaction at 13.5 and 14.8 MeV

Abstract

We have measured the 167Er(n,p)167Ho cross-sections at two different neutron energies 13.5 and 14.8MeV. Measurements were performed at Pd-300 neutron generator of Chinese Academy of Engineering Physics (CAEP) with monoenergetic neutrons produced via the 3H(d,n)4He reaction using a tritium–titanium (T–Ti) target. Induced gamma activities were measured by a high-resolution gamma-ray spectrometer with high-purity germanium (HPGe) detector. The data for 167Er(n,p)167Ho reaction cross-sections are reported to be 2.2±0.6 and 2.8±1.4mb at 13.5±0.2 and 14.8±0.2MeV incident neutron energies, respectively. The cross sections were also estimated with the TALYS-1.4 nuclear model code and compared with experimental data found in the literature, and with the comprehensive evaluation data in ENDF/B-VII.1 and JEFF-3.1/A libraries.
