Abstract
The General Fission (GEF) model is a semi-empirical model describing fission process, which combines physical concepts from quantum mechanics and statistical mechanics with specific experimental information to adjust a set of parameters suitable for different fission systems and gives reliable predictions for essentially all fission observables of a broad range of fissioning nuclei. In this work, the mass distributions of $^{233}$U neutron-induced fission are calculated using the GEF model. The results show that with the increase of incident neutron energy, the contribution of symmetric fission channel increases gradually, and the asymmetric fission channel decreases. Detailed analysis of the fragment mass distribution is performed by taking multi-chance fission into account. The contribution of (n,f) fission channel gradually decreases with the increase of incident neutron energy, while the other fission channels increases. The variation trend of the yield energy-dependence is related to the position located on the mass distribution.
