Abstract：
Based on an analysis of Kramers' stationary solution, by means of the analytical solution of the Fokker-Planck equation in a harmonical potential, we propose a simple model for the calculation of the fission rates. As an example we compute the time evolution of the fission widths of Pu²⁴⁰ for various finite friction values and compoared our results with the corresponding ones based on Kramers' formula for a large and small frictions and the transition state method.
