DOUBLE-FOLDING MODEL FOR HEAVY-ION OPTICAL-POTENTIAL - REVISED AND APPLIED TO STUDY C-12 AND O-16 ELASTIC-SCATTERING

The double-folding model is generalized for the calculation of the nucleus-nucleus potential using the new version of the density-dependent M3Y interaction which reproduces consistently the equilibrium density, and binding energy of normal nuclear matter as well as the density- and energy dependence of the nucleon optical potential. The exchange part of the heavy-ion optical potential is evaluated within a local density formalism, using the finite-range exchange components of the same interaction. The model is used successfully to describe the elastic C-12 and O-16 scattering data at low and medium energies. The influence of different density-dependent parameters (which determine different nuclear equations of state) on the description of heavy-ion scattering is also discussed.
