| Popis: | The cross sections for the $^{232}\mathrm{Th}(n,\ensuremath{\gamma})$ reaction have been measured in the neutron energy range of 11--19 MeV by using activation and offline $\ensuremath{\gamma}$-ray spectrometric techniques. The neutrons of desired energy were obtained by the $^{7}\mathrm{Li}(p,n)$ reaction using a proton beam of 13--21 MeV from the 14UD BARC-TIFR Pelletron facility at Mumbai, India. The $^{232}\mathrm{Th}(n,\ensuremath{\gamma})$ 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). |
