“…Secondly, both the T = 1 and T = 0 channel of V pn /V np are modified on USD*, labeled as USD*(V pn T =1,0 ). Our calculations for nuclei 22−24 Al and 23,24 Si are given in Table IV together with experimental data. For comparison, in the last column of the table we also give the experimental excitation energies of the corresponding states of the mirror partners of the nuclei of concern.…”

“…The original V MU parameters can reproduce well the monopole part of SDPF-M and GXPF1A interactions in sd and pf regions [15]. The validity of the V MU in shell-model calculation is examined in the psd [23] and sdpf [24,25] regions. A similar method was used in Ref.…”

“…For heavier proton-neutron open-shell nuclei such as 23,24 Al and 24 Si, additional effects may need to be considered in future studies to give a more detailed description. One effect may be the evolution of the single particle energies of 1s 1/2 orbit which are due to nuclear forces but not fully included in USD.…”

“…The depth of the potential is taken to be V 0 = 46.5 MeV, while other parameters are the same as before. The 1s 1/2 orbital in 24 Si is calculated to be weakly bound by 0.1 MeV, which is reasonable by taking into account the fact that both the ground state of 25 P and the 1/2 + 1 state of 23 Al are unbound [8]. The radial wave function of the neutron 1s 1/2 state is calculated with harmonic oscillator potential with A = 24.…”

The properties of loosely bound proton-rich nuclei around A = 20 are investigated within the framework of nuclear shell model. In these nuclei, the strength of the effective interactions involving the loosely bound proton s 1/2 orbit are significantly reduced in comparison with those in their mirror nuclei. We evaluate the reduction of the effective interaction by calculating the monopole-baseduniversal interaction (VMU ) in the Woods-Saxon basis. The shell-model Hamiltonian in the sd shell, such as USD, can thus be modified to reproduce the binding energies and energy levels of the weakly bound proton-rich nuclei around A = 20. The effect of the reduction of the effective interaction on the structure and decay properties of these nuclei is also discussed.

“…Now we know that as nuclei move away from the line of stability (Z ∼ N ), where Z (N ) is the proton (neutron) number) those magic numbers might change due to correlations and details of the nucleonnucleon interaction, e.g., the tensor-force [248][249][250][251][252][253][254]. These and other properties of nuclei far from the stability and in particular those close to the drip-line (i.e., when adding one more nucleon leads to an unbound nucleus) increased enormously the interest for low-energy nuclear physics, in particular for the prospects of its application to other areas of science [255].…”

In this review we discuss the current status of research in nuclear physics which is being carried out in different centers in the World. For this purpose we supply a short account of the development in the area which evolved over the last 9 decades, since the discovery of the neutron. The evolution of the physics of the atomic nucleus went through many stages as more data become available. We briefly discuss models introduced to discern the physics behind the experimental discoveries, such as the shell model, the collective model, the statistical model, the interacting boson model, etc., some of these models may be seemingly in conflict with each other, but this was shown to be only apparent.The richness of the ideas and abundance of theoretical models attests to the important fact that the nucleus is a really singular system in the sense that it evolves from two-body bound states such as the deuteron, to few-body bound states, such as 4 He, 7 Li, 9 Be etc. and up the ladder to heavier bound nuclei containing up to more than 200 nucleons. Clearly statistical mechanics, usually employed in systems with very large number of particles, would seemingly not work for such finite systems as the nuclei, neither do other theories which are applicable to condensed matter. The richness of nuclear physics stems from these restrictions. New theories and models are presently being developed. Theories of the structure and reactions of neutron-rich and proton-rich nuclei, called exotic nuclei, halo nuclei, or Borromean nuclei, deal with the wealth of experimental data that became available in the last 35 years. Further, nuclear astrophysics and stellar and Big Bang nucleosynthesis have become a more mature subject. Due to limited space, this review only covers a few selected topics, mainly those with which the authors have worked on. Our aimed potential readers of this review are nuclear physicists and physicists in other areas, as well as graduate students interested in pursuing a career in nuclear physics.
