“…Using such sensitivity of the barrier distribution to the deformation parameters, the quadrupole and the hexadecapole deformation parameters of the 24 Mg nucleus have been extracted recently [41]. To this end, the barrier distribution extracted from the quasi-elastic scattering for the 24 Mg+ 90 Zr system was analyzed with the Bayesian statistics.…”

The concept of compound nucleus was proposed by Niels Bohr in 1936 to explain narrow resonances observed in scattering of a slow neutron off atomic nuclei. A compound nucleus is a metastable state with a long lifetime, in which all the degrees of freedom are in a sort of thermal equilibrium. Fusion reactions are defined as reactions to form such compound nucleus by merging two atomic nuclei. Here a short description of heavy-ion fusion reactions at energies close the Coulomb barrier is presented. This includes: (i) an overview of a fusion process, (ii) a strong interplay between nuclear structure and fusion, (iii) fusion and multi-dimensional/multiparticle quantum tunneling, and (iv) fusion for superheavy elements.

“…Both the ground state and dynamical properties of nuclei are shapedependent. In heavy-ion reaction dynamics, the nuclear shape is also revealed to play important roles [1][2][3]. In practice, the nuclear shape is usually expressed by a set of deformation parameters (e.g.…”

“…Relative to the quadrupole deformation β 2 , the hexadecapole deformation is difficult to determine experimentally with good precision, primarily because of its small magnitude [1,24]. Furthermore, all the results are model dependent and quite different with big uncertainties [25].…”

The structure properties for even-even nuclei around 230U, locating on the hexadecapole-deformation island, are investigated by using the potential-energy-surface calculation within the framework of macroscopic-microscopic model. The impact of different deformation degrees of freedom (including axial and nonaxial quadrupole and hexadecapole deformations) on total energy, shell and pairing contributions is analyzed based on the projected energy-maps and -curves. The single-particle structure is presented and briefly discussed. To a large extent, much better agreement with experiment data and other theoretical results was obtained if the hexadecapole deformations, especially the axial one, were taken into account. Present results could provide useful keys to understand the effects of different quadrupole and hexadecapole deformations. Considering the least energy principle, the more reasonable deformation subspace is suggested to simultaneously include the octupole correlation.
