Determination of neutron capture cross sections of ^232Th at 14.1 MeV and 14.8 MeV using the neutron activation method

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...

Summary: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.
