Exclusion Principle and Phenomenological Optical-Model Potentials

In recent years the elastic scattering of particles by a nucleus has been successfully analyzed in terms of a simple complex-potential model. In such calculations the exclusion principle has been ignored, although for not too energetic bombarding nucleons the effect can be considerable. A modification of the optical model is proposed which takes into account the effect of the exclusion principle within the framework of a singleparticle description of the many-body problem. (W.D.M.)
