Cross section analysis of proton-induced nuclear reactions of thorium

Abstract

Production cross sections of 225,226,228Ac and 226,231Th by the proton bombardment on 232Th target at the proton energies from 10MeV to 155MeV are calculated with collective semi-classical nuclear level density model (CSCFGM) by using TALYS computer code. Collective nuclear level density effect on these reactions are investigated. The importance of collective effects (rotational and vibrational) on proton induced reactions are represented. Theoretical results are compared with the experimental data taken from EXFOR library, which shows a good agreement.
