Abstract：
A three-dimensional Langevin equation with covariant form is applied to describe the asymmetric nuclear fission. The calculations for kinetic energy and mass distribution of fission-fragments are performed in terms of the {c,h, α} parameterization,and the descent process of the fissioning nucleus from the saddle point to the scission point is simulated numerically. The dependence of the model on the choices for two types of nuclear dissipation such as two-body viscosity and one-body dissipation, as well as the scission configurations of nuclear system with finite neck is investigated.
