Abstract

Abstract The 232Th(n,γ)233Th and 232Th(n,2n)231Th reaction cross-sections have been determined for the first time at average neutron energies of 8.04±0.30MeV and 11.90±0.35MeV using activation and off-line γ-ray spectrometric technique. The neutron beam was generated using 7Li(p,n) reaction. The experimentally determined cross-sections were compared with the evaluated nuclear data libraries of ENDF/B-VII and JENDL 4.0 and are found to be in good agreement. The 232Th(n,γ)233Th and 232Th(n,2n)231Th reaction cross-sections were also calculated theoretically using TALYS 1.2 computer code and compared with the experimental data.
