Abstract

Two recipes for modeling the dynamics of the nuclear fission process are known in literature. The underlying equations contain the driving, dissipative, and random forces. The two recipes are mostly different in the prescriptions for the driving force. In this work we carefully compare these driving forces and the resulting fission rates. It turns out that the rates may be very close or
strongly different depending on the value the shell correction to the nuclear deformation energy. We give arguments in favor of one of the recipes.
