Description

The fission cross-section of the 232Th(n,f)141Ba reaction induced by neutrons around 14 MeV was measured precisely with the neutron activation and off-line gamma-ray spectrometric technique. Neutron fluence was monitored on-line using the accompanying α-particles from the 3H(2H,n)4He reaction, whereas the neutron energies were measured by the method of cross-section ratios of 90Zr(n,2n)89Zr to 93Nb(n,2n)92mNb reactions. The experimentally determined 232Th(n,f)141Ba reaction cross-sections were 12.2 ± 0.4 mb at En = 14.1 ± 0.3 MeV, 13.0 ± 0.5 mb at En = 14.5 ± 0.3 MeV and 13.3 ± 0.5 mb at En = 14.7 ± 0.3 MeV, respectively.
