A stochastic approach for fission dynamics based on one-dimensional Langevin equations was applied to investigate the effect of the nuclear dissipation on the prescission neutron multiplicity, fission probability and the fission time for the compound nucleus 210Po in an intermediate range of excitation energies 30–120 MeV. 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 0.28 ≤ ks ≤ 0.50.
