Abstract
Temperature-dependent fission barriers and fission-fragment mass distributions are calculated with an extended ver sion of the multi-modal random neck-rupture model (MM-RNRM). It is shown how the distinction between the different fission modes vanishes in going towards higher excitation energies, due to the melting of shell effects. The fission-fragment mass yield calculations are coupled to the nuclear reaction code ALICE-91, which computes the fission cross section in competition with the other reaction channels. With the combination of the temperature-dependent MM- RNRM and ALICE-91 nucleon-induced fission is investigated at energies between 10-200 MeV. Results are included for several (sub)actinide nuclei.
