Popis:	Double differential cross sections were measured for neutron emission induced by 256 MeV and 800 MeV protons incident on Li, Al, Zr, and Pb targets. The experimental spectra obtained are almost exclusively attributable to a preequilibrium emission mechanism and are compared to predictions made by several preequilibrium reaction models. The intranuclear cascade model reproduces the data quite well at both incident energies. Other approaches---the statistical multistep direct model and the hybrid model---reach the limit of applicability in their present form as the pion production threshold is crossed.
