摘要
The Th-232(n,gamma)Th-233 and Th-232(n,2n)Th-231 reaction cross-sections have been determined for the first time at average neutron energies of 8.04 +/- 0.30 MeV and 11.90 +/- 0.35 MeV using activation and off-line gamma-ray spectrometric technique. The neutron beam was generated using Li-7(p,n) reaction. The experimentally determined cross-sections were compared with the evaluated nuclear data libraries of ENDF/B-VII and JENDL 4.0 and are found to be in good agreement. The Th-232(n,gamma)Th-233 and Th-232(n,2n)Th-231 reaction cross-sections were also calculated theoretically using TALYS 1.2 computer code and compared with the experimental data.
