Dissipative dynamics of fission in the framework of asymptotic expansion of Fokker-Planck equation
The dynamics of fission has been formulated by generalising the asymptotic
expansion of the Fokker-Planck equation in terms of the strength of the
fluctuations where the diffusion coefficients depend on the stochastic
variables explicitly. The prescission neutron multiplicities and the mean
kinetic energies of the evaporated neutrons have been calculated and compared
with the respective experimental data over a wide range of excitation energy
and compound nuclear mass. The mean and variance of the total kinetic energies
of the fission fragments have been calculated and compared with the
experimental values.Comment: 13 pages, 6 figures, accepted for publication in European Physical
