“…In particular, the shoulder at prolate deformations becomes lower in energy and more pronounced. This structure is associated with the rotational band observed down to spin 2 + [38]. The gain in total deformation energy, however, is much smaller than the gain in deformation energy from the tensor terms.…”

We study systematically the impact of the time-even tensor terms of the Skyrme energy density functional, i.e. terms bilinear in the spin-current tensor density, on deformation properties of closed shell nuclei corresponding to 20, 28, 40, 50, 82, and 126 neutron or proton shell closures. We compare results obtained with three different families of Skyrme parameterizations whose tensor terms have been adjusted on properties of spherical nuclei:(i)T IJ interactions proposed in the first paper of this series [T. Lesinski et al., Phys. Rev. C 76, 014312 (2007)] which were constructed through a complete readjustment of the rest of the functional (ii) parameterizations whose tensor terms have been added perturbatively to existing Skyrme interactions, with or without readjusting the spin-orbit coupling constant. We analyse in detail the mechanisms at play behind the impact of tensor terms on deformation properties and how studying the latter can help screen out unrealistic parameterizations. It is expected that findings of the present paperare to a large extent independent of remaining deficiencies of the central and spin-orbit interactions, and will be of great value for the construction of future, improved energy functionals.

“…The next region of stability corresponds to the superdeformed shape. This state represents 4 nucleon excitation, being very much in line with [52,53]. Then appears an even more deformed state with triaxial shape, and two pronounced hyperdeformed shapes close to each other.…”

Abstract. We discuss a simple symmetry-adapted method for the determination of the shape isomers, and for the study of their possible fragmentation. In other words the connection between the quadrupole (collective) and dipole (cluster) degrees of freedom is considered in terms of an easily applicable, yet microscopic method. The energetics is taken into account by the double-folding method. Special attention is focused on those cases in which the theoretical predictions have a direct comparison with experimental observation.

“…Similar to these 1d 3/2 'extruder' states in the lower half of the 1f 7/2 shell, 1g 9/2 'intruder' states readily occur in the upper half of the 1f 7/2 shell below the doublymagic N = Z = 28 nucleus 56 Ni [23,24,25]. However, the inclusion of either the full sd, the 1d 3/2 , or the 1g 9/2 shell to the usually very successful 'pure' pf shellmodel space does not only cause a significant increase in the dimensions of the Slater determinants to be diagonalized, but also induces technical problems within the prescriptions of the spherical shell model [26].…”
