A stochastic approach based on one-dimensional Langevin equations was used to calculate the average pre-fission multiplicities of neutrons, light charged particles and the fission probabilities for compound nucleus 213Fr and results compared with the experimental data. In these calculations, a modified wall and window dissipation with a reduction coefficient, ks, has been used in the Langevin equations. It was shown that the results of the calculations are in good agreement with the experimental data by using values of ks in the range .
