Mass and charge attributes of heavy ion potentials obtained by inversion

Abstract

Potentials are obtained using a WKB inverse scattering technique that is based upon S functions derived from strong absorption model fits to the elastic-scattering cross sections for 1503 MeV O16 ions on C12, Ca40, Zr90, and Pb208. A systematic study of the mass (charge) dependence of the heavy ion nuclear potential at this energy is the result. In this context the dependence of the extracted nuclear potential on the assumed Coulomb interaction between the heavy ions is also considered. With increasing target mass the choice of representative Coulomb field is important in specification of the hadronic interaction component of the inversion potential. © 1991 The American Physical Society.
