Dynamical simulation of neutron-induced fission of uranium isotopes using four-dimensional Langevin equations

Abstract

Four-dimensional Langevin equations have been suggested for the dynamical simulation of neutron-induced fission at low and medium excitation energies. The mass distribution of the fission fragments, the neutron multiplicity, and the fission cross section for the thermal and fast neutron-induced fission of $^{233}\mathrm{U},\phantom{\rule{0.16em}{0ex}}^{235}\mathrm{U}$, and $^{238}\mathrm{U}$ is studied by considering energy dissipation of the compound nucleus through the fission using four-dimensional Langevin equations combined with a Monte Carlo simulation approach. The calculated results using this approach indicate reasonable agreement with available experimental data.
