EFFECTIVE LOCAL INTERACTIONS AND THE EQUATION OF STATE FOR NUCLEAR-MATTER AND FINITE NUCLEI

Differences in the evaluation of the saturation properties of infinite nuclear matter and finite nuclei are discussed. It is demonstrated that ground-state properties of finite nuclei are much more affected by the finite range of realistic nucleon-nucleon interactions than the saturation point of nuclear matter. Due to surface effects, a larger incompresibility for finite nuclei is obtained as compared to nuclear matter. Local nucleon-nucleon interactions are determined, which simulate the main features of the Brueckner G-matrix and allow for a simple calculation and analysis of the ground-state properties. These effective local interactions of finite range could be very useful in dynamical calculations of heavy-ion scattering.
