A finite-range momentum and density dependent two-body effective interaction is employed for this purpose. The role of mass, isospin and equation of state (EoS) on these quantities is also investigated; our calculated results are in consonance with the available experimental data.20 pages, 8 figures, revtex4; modifications in text and figuresNuclear Theorytext
