The mass distributions of fragments produced by proton-induced fission of 232Th, 235U, 238U, and 237Np at proton energies of 50 and 96 MeV have been measured. The measurements were carried out at The Svedberg Laboratory, Uppsala, Sweden using a high-precision time-of-flight spectrometer for fission fragments and fission neutrons. The measured mass distributions are compared to ones calculated using the TALYS code. Using proton-induced reactions to simulate the outcome of more difficult measurements with neutron beams is discussed.
