In this paper differential (p, xn) cross sections d{sup 2}{sigma}/d{Omega}E{sub n}, from the thin targets of beryllium, carbon, oxygen, aluminum, iron, lead, and {sup 238}U for 256-MeV protons are measured. Time-of-flight techniques are used to identify and discriminate against backgrounds and to determine the neutron energy spectrum. Comparison of the experimental data with intranuclear-cascade evaporation-model calculations using the HETC code showed discrepancies of as much as a factor of 7, notably at 7.5 and 150 deg.
