A stochastic approach that treats fission dynamics on the basis of one-dimensional Langevin equations was used to investigate the effect of the nuclear dissipation on the pre-scission neutron multiplicity and fission probability for the compound nucleus in an intermediate range of excitation energies. A modified wall and window dissipation with a reduction coefficient, , has been applied in the Langevin equations. It was shown that by using values of in the range , the results of the calculations are in good agreement with the experimental data.
