Based on an analysis of Kramers' stationary solution, by means of the analytical solution of the Fokker-Planck equation in a harmonic potential, we propose a simple model for the calculation of the fission rate. As an example we compute the time evolution of the fission width of /sup 240/ Pu for various finite friction values and compare our results with the corresponding ones based on Kramers' formula for large and small frictions, and the transition state method.
