Abstract：
The ²³²Th(n,γ)²³³Th neutron capture reaction cross sections were measured at average neutron energies of 14.1 MeV and 14.8 MeV using the activation method. The neutron flux was determined using the monitor reaction ²⁷Al(n,α)²⁴Na. The induced gamma-ray activities were measured using a low background gamma ray spectrometer equipped with a high resolution HPGe detector. The experimentally determined cross sections were compared with the data in the literature, and the evaluated data of ENDF/B-VⅡ.1, JENDL-4.0u+, and CENDL-3.1. The excitation functions of the ²³²Th(n,γ)²³³Th reaction were also calculated theoretically using the TALYS1.6 computer code.
