- Description
- We analyze the recent experimental data on photofissility for <math>^{237}Np, ^{238}U\,\!</math>, and <math>^{232}Th \,\!</math> at incident photon energies above 200MeV. For this analysis, we developed a Monte Carlo algorithm for the nuclear evaporation process in photonuclear reactions. This code is used in association with the multi-collisional model for the photon-induced intranuclear cascade process. Our results show a good quantitative and qualitative agreement with the experimental data. It is shown that the emission of protons and alpha particles at the evaporation stage is an important component for the non-saturation of the actinides photofissility up to, at least, 1GeV.
