Neutron-Proton Scattering at 90 Mev

Abstract
An investigation of 90-Mev neutrons scattered by protons has been conducted with a cloud chamber filled with hydrogen or with a mixture of methane and hydrogen in a magnetic field of 22 000 gauss. The neutron energy spectrum has a full width at half-maximum of about 30 Mev. The neutron scattering angles range from 8° to 180° in the center-of-mass system. The differential scattering cross section is found to have a symmetry about 90° in the center-of-mass system.
