Interaction potential between heavy ions

The semi-microscopic potential between heavy ions is evaluated for various colliding ions in the approach of frozen densities in the framework of the extended Thomas-Fermi approximation with h(2) correction terms in the kinetic energy density functional, The proton and neutron densities of each ion are obtained in the Hartree+Fock-Bogoliubov approximation with SkM* parameter set of the Skyrme force. An expression for the ion-ion potential well fits the semi-microscopic potentials in the wide range of both colliding ions and distances between them. (C) 2002 Elsevier Science B.V.
