Determination of ground-state nuclear properties of nuclei such as binding energy, nucleon separation energy, radii of nuclei, quadrupole moments and deformation parameter are an important research subjects in nuclear physics. There are many data of nuclear ground-state properties of nuclei in literature as a result of long term experimental and theoretical studies. Beside, investigation of nuclear ground-state properties by regarding an isotopic or isotonic chain is attractive because it can provide better understanding of many nuclear phenomena. Because N=40 neutron number is sub shell closure, investigation around this region is a test for nuclear models. For investigation of nuclear properties of nuclei, many experimental studies are performing and many nuclear models have been developed. One of them is mean field approach. In this approach, it is assumed that a nucleon move independently in a mean field created by other nucleons. As examples for mostly used mean field approaches, Hartree-Fock-Bogoliubov (HFB) method and relativistic mean field (RMF) model can be given. In this work, HFB method with a Skyrme type parameter set SLy4 has been used for investigation of ground-state properties of even-even N=40 isotones starting from the proton number Z = 18 to Z = 42. The binding energy per nucleon, charge radii and two-neutron separation energy have been calculated and compared with available experimental data and those of other nuclear models. By this work, it has been concluded that the predictions of the HFB method for binding energy and charge radii are in agreement with experimental data.
