Neutron-Deuteron Scattering at High Energies

Abstract

Stationary-state perturbation theory is applied to the problem of $n-d$ scattering at high neutron energies. The Born approximation is used and exchange, but not tensor, forces are considered. It is shown that the $n-d$ cross section, even in the case of general exchange forces, is made up of three distinct contributions: the cross sections for the scattering of the incoming neutron from the bound proton or neutron, respectively, averaged over the momentum distribution of the particle in the deuteron; and the cross-terms due to interference and the Pauli principle.
