Abstract
We obtained a density-dependent analytical expression of binding energy per nucleon for different neutron-proton asymmetry of the nuclear matter (NM) with a polynomial fitting, which manifests the results of effective-field theory motivated relativistic mean-field (E-RMF) model. This expression has the edge over the Brückner energy density functional [Phys. Rev. 171, 1188 (1968)] since it resolves the Coster-Band problem. The NM parameters like incompressibility, neutron pressure, symmetry energy, and its derivatives are calculated using the acquired expression of energy per nucleon. Furthermore, the weight function calculated by E-RMF densities are folded with calculated NM parameters within coherent density fluctuation model to find the properties of closed or semiclosed-shell even-even , and nuclei. The values obtained for the neutron pressure , symmetry energy , and its derivative known as the slope parameter lie within a narrow domain whereas there is a large variation in isoscalar incompressibility and surface incompressibility while moving from light to heavy nuclei. The sizable variation in and for light and heavy nuclei depicts their structural dependence due to the peculiar density distribution of each nucleus. A comparison of surface quantities calculated in the present work has also been made with ones obtained via Brückner energy density functional.
