Abstract：
By using the {c,h,α} parameterization to describe the deformation process of heavy nuclei, a Langevin equation for fission dynamics with neutron emission is presented and the Monte-Carlo calculations of pre-scission neutron multiplicities are performed. The effect of different damping coefficients on the result is compared, especially the distributions of neutron emission when the system first and last passes the saddle point are distinguished.
