“…The pairing energy and the Fermi energy are the important features in the description of the properties of nuclei. From the Fermi energy, we can obtain an important information, especially about the exotic nuclei near/at the neutron drip-line region by showing the boundaries of the nuclear landscape [25,26,33,34].…”

This work aims at systematic investigations of the proton and neutron pairing properties and Fermi energies in the region from the proton drip-line to the neutron drip-line. In order to obtain a more accurate mass formula with the Skyrme (SKI3) force, the global descriptive power of the Skyrme–Hartree–Fock–Bogoliubov model for pairing properties is applied. Systematic Skyrme–HFB calculations with a mixed volume-surface pairing are carried out to study the ground-state proton pairing gap, neutron and proton pairing energies, and the neutron and proton Fermi energies for about 2095 even-even nuclei ranging from 2 ≤ Z ≤ 110 to 2 ≤ N ≤ 236 . The calculated values of proton pairing gaps are compared with experimental data, by using the difference-point formulas Δ(3), Δ(4), and Δ(5), and compared with the proton pairing gap in the Lipkin–Nogami model. It is shown that the Skyrme (SKI3) force with the mixed volume-surface pairing can be successfully used for describing the ground-state proton pairing gap, proton and neutron pairing energies, and proton and neutron Fermi properties of the investigated nuclei, in particular, the neutron-rich nuclei and the exotic nuclei near the neutron drip-line. On the other hand, the calculated proton pairing gap shows the acceptable agreement with the available experimental values of the proton pairing gap with the use of the difference-point formulas Δ(3), Δ(4), and Δ(5) and with the data of the Lipkin–Nogami model over the whole nuclear chart.

“…Despite passing more than a century on the discovery of nuclear physics, scientists are still seeking to reach a universal theory that be able to clarify the general description about nuclear structure properties and the shape of nucleus of all well-known nuclei with high accuracy [1,2,3]. Therefore, the essential objective of theoretical researches in this field is to understand the reaction properties, shape, size and structure of each of the nuclei in the periodic table [4,5,6].…”

Ground State (GS) Properties of Even-Even 30−92 20 Ca isotopes have been studied in frame of Skyrme Hartree-Fock-Bogoliubov using computer program HFBTHO V3.00 with three types of Skyrme interactions (HFB9, SLY4 and SLY5). The calculated nuclear properties including (average binding energy ( BE ⁄ A ), two nucleon separation energy (S 2N ), two neutron shell gap (δ 2N ), quadrupole deformation parameter (β 2 ), charge radii (R ch ), neutron and proton radii (R N , R P ) and skin thickness) were compared with the available experimental data and with the results of Finite Range Droplet Macroscopic method (FRDM) and Relativistic Mean Field (RMF) theory. According to Binding energy ( BE ⁄ A ), it turns out that it increases directly with increase directly with the increases in neutron number until arrive its Max. value at the region between (N=20-30) which is due to the effect of the two magic numbers (N=20,28), after this region ( BE ⁄ A ) start to decrease progressively.

This study is an investigation of the effect of the pairing strength using different types of pairing (surface, volume and mixed surface–volume pairing) on the ground state properties of even and odd Mg isotopes. The Hartree–Fock–Bogoliubov (HFB) theory and two types of Skyrme forces, SKI3 and SLY6, were employed in our calculations. The pairing strength values are modified at each execution of the HFBTHO code to obtain the experimental values of binding energy for the investigated even and odd isotopes separately. Then a new formula for pairing strength for each even and odd isotope independently for all the pairing, surface, volume and mixed surface–volume types is developed by fitting the pairing strength values to the mass number. Based on the newly generated formulas for pairing strength, some of the calculated ground state properties are found to depend strongly on the pairing strength values and the pairing type also plays an essential role in providing accurate results.
