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

Abstract

Abstract：The 232 Th(n, γ) 233 Th 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 27 Al(n,α) 24 Na.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 literatures data, evaluated data of ENDF/B-VII, JENDL-4.0, and CENDL-3.1. The Excitation functions of 232 Th(n,γ) reaction were also calculated theoretically using the TALYS 1.6 computer code.

Development of a compact D-D neutron generator

“…Neutron generator based on 2 H(d,n) 3 He (D-D) or 3 H(d,n) 4 He (D-T) fusion reactions is advantageous in its relative higher neutron yield achieved under a lower deuteron beam energy. This neutron generator has extensive application in the fields of the nuclear data measurement [1,2], neutron activation analysis [3][4][5] and neutron radiography [6][7][8].…”
