Abstract
Using one of the recent Bonn potentials, an energy- and density-dependent interaction for nucleon-nucleus scattering is derived by solving the Bethe-Goldstone equation for two nucleons interacting in the presence of infinite nuclear matter at several incident energies below 425 MeV. Some of the approximations involved in the construction of the effective interaction are discussed and several of its dynamical properties are examined. Selected properties of the present interaction are also compared with those of a similar G-matrix interaction based on the Paris potential as well as with those of a recent t-matrix interaction based directly on nucleon-nucleon phase shifts. The role of medium corrections as well as the utility of the present interaction are studied by applying it to a variety of transitions in nucleon-nucleus scattering where important constraints on the transition densities are available from electron scattering.
