Description

Multi-modal fission of the uranium nucleus at the low excitation energy has been dynamically investigated. The multi-dimensional Langevin equation is used for the dynamical calculation. We used the potential energy taking account of the microscopic energy which depends on the excitation energy. We obtained the peaks of the mass distribution and the total kinetic energy (TKE) distribution. The former is consistent with experimental results and the latter is consistent with experimental systematics. We study the evolution of the mass-asymmetry of the fragments in the dynamical process from the second saddle to the scission
