Abstract:

A nonlocal optical model is used to analyze proton-nucleus scattering data for target nuclei with nucleon numbers ranging from 12 to 208 and for proton energies from 16 to 65 MeV. The real part is provided by a recently-formulated simplified RGM method called model K. The imaginary part is purely phenomenological, and is obtained by simply adopting the imaginary potentials determined previously by other investigators with the usual local optical model. The influence of the Perey effect is taken into account by the introduction of an energy-dependent multiplicative factor. The results show that, with minimal effort, a good agreement between calculation and experiment for both the differential scattering cross section and the analyzing power can be achieved. This indicates that model K represents a simple and realistic approach, and can be used to construct a global nonlocal optical model for the systematic study of all existing nucleon-nucleus scattering data.
