Description

The fission cross sections of the symmetric SL-mode and the asymmetric lumped (S1+S2)-mode of the 238U(n,F), 235U(n,F), 232Th(n,F), and 238U(p,F) reactions are calculated up to En=200 MeV within a statistical model. To reproduce the measured branching ratio of symmetric and asymmetric fission events in the 238U(n,F) reaction, a preferential contribution of fission from neutron-deficient nuclei is assumed. This assumption is of critical importance to reproduce the observed 232Th(n,F) cross section. The branching ratio of symmetric and asymmetric fission events is shown to increase, with the increase of the incident neutron energy, faster for the higher fissility of the target nuclide
