MODEL-UNRESTRICTED NUCLEUS-NUCLEUS SCATTERING POTENTIALS FROM MEASUREMENT AND ANALYSIS OF O-16-16 SCATTERING(O)

The elastic scattering cross section for O-16 ions on O-16 targets has been measured with high accuracy over large angular ranges at inciden t energies from 250 to 704 MeV. From these data which sample both diff ractive and refractive scattering processes, we extract the underlying scattering potentials using model-unrestricted analysis methods. ?The extracted potentials fit very well into the systematics found in ligh t-ion scattering. The real potential parts also compare very favourabl y with microscopically calculated folding potentials based on a weak d ensity-dependence of the underlying effective nucleon-nucleon interact ion at large overlap densities.
