The cross sections for the ²³²Th(n, γ ) reaction have been measured in the neutron energy range of 11–19 MeV by using activation and offline γ -ray spectrometric techniques. The neutrons of desired energy were obtained by the ⁷Li(p, n) reaction using a proton beam of 13–21 MeV from the 14UD BARC-TIFR Pelletron facility at Mumbai, India. The ²³²Th(n, γ ) reaction cross sections were calculated using the computer code TALYS-1.8. The uncertainties in the measurement have been studied using covariance analysis of the experimental data. The results from the present work have been compared with the evaluated data of ENDF/B-VII.1 and JENDL-4.0 as well as the theoretically calculated values based on TALYS-1.8, and were found to be in good agreement. The outcome of the present work is important for the development of future fast reactors and accelerator driven subcritical systems (ADSs).
