Proton-deuteron scattering at 77 MeV

Abstract

The Oxford 12 cm deuterium bubble chamber has been used to examine the reactions p+ d→ p+ d, p+ d→ p+ p+ n , at an incident proton energy of 77 MeV. The total cross-section (excluding elastic scattering below 10° c.m.) is found to be 146±8 mb. The elastic differential cross-section, measured over the angular range 5°–180° (c.m.) is compared with the impulse approximation theory. The low statistical accuracy of the experiment does not allow a detailed examination of the inelastic events to be made, but some general features are discussed. Chew-Low extrapolations have been performed to determine the free p-p and n-p cross sections.
