The Analysis of Neutron-Proton Scattering with Tensor Forces

Abstract

The expansion in energy of the cross section for central force scattering proposed by Chew and Goldberger is extended to tensor force scattering. The change due to the addition of tensor forces, in both the effective range and in the shape dependent coefficient, is shown to be small. Hence, as has been previously shown by Blatt and Jackson for central forces, scattering below 10 Mev is practically independent of the potential shape assumed and is completely characterized by the scattering length and effective range.
