“…Regarding 23 Al- 23 Ne (J π T = 5/2 + 3/2) pair nuclei, the theoretical calculations are the same way as in 17 Ne- 17 N nuclei but with different model space and interactions. Firstly, the configurations (1s 1/2 ) 4 (1p) 12 plus 7 nucleons moved in sd orbits are used for the core nucleons 22 Mg (J π T = 0 + 1) and 22 Ne (J π T = 0 + 1). In sd model space all orbits in 2s-1d shells are considered where the universal shell model USD [27] is used.…”

“…In sd model space all orbits in 2s-1d shells are considered where the universal shell model USD [27] is used. To reproduce the core radii a value of b = 1.74 fm is used for 22 Mg and 22 Ne. While the outer nucleon must be in 1d 5/2 with value b v = 3.4 fm for 23 Al and b v =1.75 fm for 23 Ne.…”

“…Secondly, the sdpfwa [28] interaction is used for the core of 23 Al - 23 Ne nuclei with configuration (1s 1/2 ) 4 (1p) 12 plus 7 nucleons moved in sdpf orbits are used for the core nucleons 22 Mg (J π T= 0 + 1) and 22 Ne (J π T= 0 + 1). A value of b = 1.7 fm is used for 22 Mg and 22 Ne. while the values b v = 3.45 fm and b v = 1.72 fm are used for the outer nucleon (which is assumed to be in a pure 1d 5/2 ) in 23 Al and 23 Ne, respectively.…”

In terms of the core nucleus plus valence nucleon, shell-model calculations using two model spaces and interactions, the relationship between a nucleus' proton skin, and the difference in proton radii of mirror pairs of nuclei with the same mass number are investigated. In this work, two pairs of mirror nuclei will be studied: 17Ne-17N and 23Al-23Ne. For 17Ne-17N nuclei, p-shell and mixing of psd orbits are adopted with Cohen-Kurath (ckii) and psdsu3 interactions. While for 23Al-23Ne, the sd-shell and sdpf shell are adopted with the universal shell model (USD) and sdpfwa interactions. Also, the ground state density distributions, elastic form factors, and root mean square radii of these pairs' nuclei are studied and compared with available experimental data. . In general, it was found that the rms radius of the valence proton(s) is larger than that of the valence neutron(s) in its mirror nucleus. The results show that these nuclei have the exotic structure of a halo or skin.

The self-consistent Hartree-Fock (HF) calculations with several Skyrme parameterizations; SKM, SKM*, SLY4, SKxs25, MSK7, SKO, SKxta, and SKxtb have been used to investigate some static nuclear ground-state properties of some Chromium (50-54 Cr) isotopes. The nuclear ground state charge, mass, neutron and proton densities with the corresponding root mean square radii, the charge form factors, the total binding energies and the neutron skin thickness can be calculated. The calculations are performed using NuShellX@MSU code, where the deduced results led to specifying one set or more of Skyrme parameterizations that used to achieve the best agreement with the available experimental data.
