Neutron-Proton Scattering at 27 Mev

Abstract
Monoenergetic neutrons of energy 27.2 Mev were produced by 10-Mev deuterons incident on a gaseous tritium target. Protons recoiling from the neutrons were observed in a fourfold coincidence proportional counter telescope. The angular distribution of neutrons scattered through angles in the range from 180° to 76° in the CM system was measured. The observed ratio of scattering at 180° to that at 90° was 1.28±0.10.
