“…The parameter β 2 is directly proportional to the intrinsic mass quadrupole moment. For all three functionals the calculated equilibrium shape of 36 Ar is a slightly oblate, axially symmetric quadrupole ellipsoid with β 2 ≈ −0.2. For the equilibrium deformation and few additional values of β 2 , in the insets of Fig.…”

“…In principle a nuclear EDF can incorporate all short-range correlations related to the repulsive core of FIG. 1: (color online) Neutron single-particle levels of 36 Ar that correspond to the SCMF solutions calculated with the Skyrme functional SLy4, the Gogny effective interaction D1S, and the relativistic density functional DD-ME2. The levels are labelled by the Nilsson quantum numbers, and dotted lines denote the position of the Fermi level.…”

“…As an illustration in Fig. 2 we display the binding energies of the self-conjugate nucleus 36 Ar as functions of the axial quadrupole deformation parameter β 2 , calculated with SLy4 and D1S using the Hartree-Fock-Bogoliubov (HFB) model [23,27], and with the functional DD-ME2 employing the relativistic Hartree-Bogoliubov (RHB) approach [18]. Pairing correlations are taken into account by a delta-pairing force for calculations with the Skyrme functional, whereas for the RHB calculations with DD-ME2 the pairing interaction is separable in momentum space, and determined by two parameters adjusted to reproduce the Gogny pairing gap in symmetric nuclear matter [28].…”

“…A certain degree of localization of nucleonic densities is already present in mean-field ground-state configurations [4,34,35], and this facilitates the formation of cluster structures in excited states. Close to the particle emission threshold continuum effects become important for a quantitative description of nuclear clustering [36]. Deformation in light nuclei plays, of course, an important role in the formation of clusters [1,2,6,31,37].…”

The framework of nuclear energy density functionals is applied to a study of the formation and evolution of cluster states in nuclei. The relativistic functional DD-ME2 is used in triaxial and reflection-asymmetric relativistic Hartree-Bogoliubov calculations of relatively light N = Z and neutron-rich nuclei. The role of deformation and degeneracy of single-nucleon states in the formation of clusters is analyzed, and interesting cluster structures are predicted in excited configurations of Be, C, O, Ne, Mg, Si, S, Ar and Ca N = Z nuclei. Cluster phenomena in neutron-rich nuclei are discussed, and it is shown that in neutron-rich Be and C nuclei cluster states occur that are characterized by molecular bonding of α-particles by the excess neutrons.

“…Other models start from a molecular viewpoint that employs composite particles, such as the α-particles as the building blocks for nuclear structure. A major task is underway to connect the two seemingly disjoint points of view and how nuclear excitations can emerge from a unified picture of the nucleus [257][258][259][260][261][262][263][264][265][266][267][268][269][270][271][272].…”

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.
