Investigation of nuclear structure of 30–44S isotopes using spherical and deformed Skyrme–Hartree–Fock method

Abstract

Nuclear many-body system is usually described by a mean-field built upon a nucleon–nucleon effective interaction. In this work, we investigate ground state properties of the sulfur isotopes covering a wide range from the line of stability up to the dripline region (30–44S). For this purpose the Hartree–Fock mean field theory in coordinate space with a Skyrme parameterization SkM* has been utilized. In particular, we calculate the nuclear charge, neutrons, protons, mass densities, the associated radii, neutron skin thickness and binding energy. The charge form factors have been also investigated using SkM*, SkO, SkE, SLy4 and Skxs15 Skyrme parameterizations and the results obtained using the theoretical approach are compared with the available experimental data. To investigate the potential energy surface as a function of the quadrupole deformation for isotopic sulfur chains, Skyrme–Hartree–Fock–Bogoliubov theory has been adopted with SLy4 parameterization.
