The differential elastic scattering, total elastic scattering, and elastic transport cross sections for U238, U235, and Pu239 for 0.5- and 1.0-Mev neutrons are presented. The nonelastic reaction cross sections are given for these three materials for neutron energies of 0.25, 0.5, and 1.0 Mev and in addition for U238 for 0.15-Mev neutrons. The inelastic scattering cross sections for the excitation of the two lowest levels in U238 are also presented for neutron energies of 0.15, 0.25, and 0.5 Mev.
