  Intermediate energy data of proton-induced fission on 241Am, 238U and 237Np
targets were analysed and investigated using the computational simulation code
CRISP. Inelastic interactions of protons on heavy nuclei and both symmetric and
asymmetric fission are regarded. The fission probabilities are obtained from
the CRISP code calculations by means of the Bohr-Wheeler model. The fission
cross sections, the fissility and the number of nucleons evaporated by the
nuclei, before and after fission, are calculated and compared with experimental
data. Some of the model predictions agree completely with the data. We conclude
that our two step model of the CRISP code provides a good description of
intermediate energy proton-induced fission.
