Abstract
The intranuclear cascade-evaporation model of a high-energy nucleon-meson transport code has been used to calculate neutron production from nonelastic interactions of 585 MeV protons with C, Al, Fe, Nb, In, Ta, Pb, and U targets at emission angles of 30°, 90°, and 150°. These model predictions are compared with measurements of the double differential cross sections σ/dΩ of neutrons with kinetic energies between 0.9 and 585 MeV. In general, the model predicts approximately the correct neutron production in the evaporation region, whereas in the high energy region ( MeV) systematic discrepancies between measurements and model predictions occur. These increase rapidly with increasing neutron energy and increasing emission angle.
