Elasticn−dScattering with the Reid Interaction

Abstract

For the case of the Reid soft-core potential the elastic neutron-deuteron scattering is studied. The three-nucleon equations are solved exactly for the pure $s$-wave parts of the two-nucleon $T$ matrix while the higher partial-wave components of the force are treated perturbatively. Results are presented at 14.1 and 46.3 MeV. In particular, it is found that the pronounced minimum in the elastic cross section at higher energies, calculated with pure $s$-wave interactions, is filled in predominantly by the $d$-wave component of the deuteron.
