Effective interactions in the proton optical-model potential

A six-parameter optical model is developed in which the real central part is calculated by folding several effective nucleon-nucleon interactions into matter distributions which reproduce single-particle binding energies and electron scattering data. A simple local approximation is made to take into account the exchange term. It is concluded that the density-dependent effective interactions derived from nuclear-structure calculations are also appropriate for nucleon-nucleus scattering. Off-shell effects are apparent from the worsening of the quality of fit for light nuclei.

Ambiguities and systematics in the real central part of the optical-model potential

An analytical description is presented which accounts for both the discrete and continuous ambiguities in the real central part of the optical-model potential. This procedure allows a systematic representation of the real central parts of the optical-model potentials to be made for p, d, 3He and 4He projectiles, and indicates which potential family is most appropriate for each projectile.

On the real central part of the proton optical model potential

The recent results of Perey and Perey on the analysis of 11 MeV proton differential elastic scattering and polarization data are shown to have a simple interpretation, not requiring an energy dependent geometry as suggested by these authors.
