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 d2σ/dΩdTn 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 (En20 MeV) systematic discrepancies between measurements and model predictions occur. These increase rapidly with increasing neutron energy and increasing emission angle.
