“…There is a considerable interest to the study of cluster structures and extremely deformed shapes in light nuclei [1][2][3][4][5][6][7][8][9][10]. Many of these structures are described in terms of clusters, the simplest one being the α-particle [2,3].…”

From superdeformation to extreme deformation and clusterization in the N ∼ Z nuclei of the A ∼ 40 mass region. A systematic search for extremely deformed structures in the N ∼ Z nuclei of the A ∼ 40 mass region has been performed for the first time in the framework of covariant density functional theory. At spin zero such structures are located at high excitation energies which prevents their experimental observation. The rotation acts as a tool to bring these exotic shapes to the yrast line or its vicinity so that their observation could become possible with future generation of γ−tracking (or similar) detectors such as GRETA and AGATA. The major physical observables of such structures (such as transition quadrupole moments as well as kinematic and dynamic moments of inertia), the underlying single-particle structure and the spins at which they become yrast or near yrast are defined. The search for the fingerprints of clusterization and molecular structures is performed and the configurations with such features are discussed. The best candidates for observation of extremely deformed structures are identified. For several nuclei in this study (such as 36 Ar), the addition of several spin units above currently measured maximum spin of 16 will inevitably trigger the transition to hyper-and megadeformed nuclear shapes.

“…Another case of such structures is linear chain of three α clusters, suggested about 60 years ago [17]; it was recently studied in the CRMF theory in Ref. [8]. This exotic structure ("Hoyle" state) plays a crucial role in the synthesis of 12 C from three 4 He nuclei in stars [18].…”

“…Theoretical studies predict the rotational bands with the linear-chain configurations in C isotopes [12][13][14][15][16][17][18][19][20][21][22]. It was pointed out that the motion of the valence neutron can be qualitatively interpreted in terms of the molecular orbits analogous to the Be isotopes [23][24][25][26][27][28][29], which are called π and σ orbits.…”

Three-body decay of linear-chain states in C14

The decay properties of the linear-chain states in 14 C are investigated by using antisymmetrized molecular dynamics. The calculation predicts two rotational bands with linear-chain configurations having the π -bond and σ -bond valence neutrons. For the π -bond linear-chain, the calculated excitation energies and the widths of α-decay to the ground state of 10 Be reasonably agree with the experimental candidates observed by the α + 10 Be resonant scattering. On the other hand, the σ -bond linear-chain is the candidate of the higher-lying resonant states reported by the breakup reaction. As the evidence of the σ -bond linear chain, we discuss its decay pattern. It is found that the σ -bond linear chain not only decays to the excited band of 10 Be but also decays to the three-body channel of 6 He + α + α, and the branching ratio of these decays are comparable. Hence, we suggest that this characteristic decay pattern is a strong signature of the linear-chain formation and a key observable to distinguish two different linear chains.

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.
