Popis: The 232Th(n, γ)233Th reaction cross-section has been determined for the first time using an activation and off-line γ-ray spectrometric technique at average neutron energies of 5.9 ± 0.6 MeV and 15.5 ± 0.7 MeV. The 232Th(n, 2n)231Th reaction cross-section has also been determined at average neutron energy of 15.5 ± 0.7 MeV using the same technique. The 7Li(p, n) reaction was used to generate neutron beam. The experimentally determined cross-sections were compared with the latest available evaluated nuclear data libraries of ENDF/B-VII, JENDL 4.0 and JEFF 3.1 and found to be in good agreement. The 232Th(n,γ)233Th and 232Th(n, 2n)231Th reaction cross-sections were also calculated theoretically using the nuclear-model-based computer code TALYS 1.2 and compared with the experimental data.
