Abstract: In the present work, the nuclear structure of closed-shell neutron-rich nuclei: ^{40, 48}Ca, ⁹⁰Zr, ¹¹⁶Sn, ¹⁴⁴Sm and ²⁰⁸Pb, has been investigated in the framework of self-consistent Hartree-Fock (HF) with 20 types of Skyrme interactions. The binding energies per nucleon (B/A), charge radii (R_ch), neutron radii (r_n), proton radii (r_p) and neutron skin thickness (R_skin) were calculated and compared with the available experimental data. The studied observables are useful for analysing nuclear structure and provide information about the nuclear shape; hence, the calculated values of the present work were supported by statistical calculations by determining and discussion the statistical linear Pearson coefficient.

Keywords: self-consistent Hartree-Fock; Skyrme interaction; binding energy; neutron skin thickness; neutron; proton and charge radii.
