Interactions for inelastic scattering derived from realistic potentials

An effective local interaction for inelastic scattering is derived by fitting the matrix elements of a sum of Yukawas and, for the tensor force, other closely related forms, to three selected sets of G-matrix elements. The ranges were selected to ensure OPEP tails in the relevant channels as well as a short-range part which simulates the "σ-exchange" process. Some of the implications of the various parts of the interaction are discussed in a distorted-wave context.
