400-Mev Neutron-Proton Scattering

Abstract
The angular distribution of neutron-proton scattering has been measured at a neutron energy of 400 Mev, with energy resolution of 7 percent. The counter telescope used to detect recoil protons was calibrated in an auxiliary experiment which also gave information about proton-proton scattering at several energies in the 400-Mev region.
