NUCLEAR GROUND-STATE PROPERTIES AND ION-ION POTENTIALS IN SEMICLASSICAL CALCULATIONS WITH THE GOGNY FORCE

The ground-state properties of magic nuclei have been studied by means of the Gogny force within the Hartree-Fock scheme using the Slater ap proximation for the exchange part. A similar analysis has been carried out within the semiclassical framework by considering the extended Th omas-Fermi approach for the kinetic energy density. Comparisons with t he complete Hartree-Fock results are made. The ion-ion potential for t wo colliding nuclei has been obtained in the energy density functional and the double-folded model approaches by using self-consistent semic lassical densities calculated with the Gogny force. These potentials h ave been applied in the study of Ca-40-Ca-40 elastic scattering.
