Neutron induced reaction cross-section of 232Th and 238U at the neutron energies of 2.45 and 14.8 MeV

Abstract

For 232Th and 238U, the (n,γ) reaction cross-sections at the neutron energies of 2.45 and 14.8 MeV as well as the (n,2n) reaction cross-sections at 14.8 MeV have been determined using activation and off-line γ-ray spectrometric technique. The (n,γ) and (n,2n) reaction cross-sections of 232Th and 238U were also calculated theoretically using the TALYS 1.6 computer code. The present data and literature data in a wide range of neutron energies were compared with the evaluated data of ENDF/B-VII.1, JENDL-4.0, JEFF-3.1/A and CENDL-3.1 and theoretical value of TALYS to examine the systematics of (n,γ) and (n,2n) reaction cross-sections.
