Abstrakt: A new model for the effective two-body nucleon-nucleon interaction has been recently successful in calculation of ground state properties of spherical, doubly closed shell nuclei from 16O to 208Pb [1] and nuclear matter and neutron star properties [2]. The application of the density dependent finite range separable monopole (SMO) interaction has been now extended to axially symmetrical deformed nuclei [3]. In the present paper we report on HF+BCS calculation of ground-state properties of even-even spherical and deformed N = Z and proton-rich nuclei between the N = Z and the proton-drip line for 28≤Z≤50. The SMO results shown include total energy surfaces and deduced shapes, single-particle energies, two-dimensional distribution of nucleon densities, charge radii and two-proton separation energies. A comparison is made with results obtained using the SkO Skyrme interaction and some other theoretical models as well as with experimental data, where available. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
