Abstract
In order to verify the validity for the resonance analysis, we also investigated the neutron self-shielding and multiple-scattering effects on the neutron capture cross sections obtained for 232Th samples with three different thicknesses. The correction factors were estimated by the Monte Carlo simulation using the evaluated cross sections in JENDL-4.0 and the cross section data revised by the present resonance analysis. The comparison between the capture cross sections corrected with the JENDL-4.0 is consistent with the resonance analysis results. Moreover, it was confirmed that the revised cross section data enable the correction factors to reproduce the experimental results for the 69.2- and 120.9-eV resonances. In the case of 170.4-eV resonance, the disagreement between the experimental results was not improved in this study. Therefore, further study is necessary to improve the resonance data.
