“…Systematic spin assignments have also been made for these isotopes in Refs. [28,29]. The systematic studies make use of the fact that the ν(h 11/2 ) ⊗ π (h 11/2 ) configurations are known to be well deformed and, as a result, the excitation energies of states within the bands vary smoothly as a function of neutron number; this trend is observed in the π (h 11/2 ) bands of the odd-A 117−133 Cs isotopes, and in the ground-state bands of the even-even Z = 54 116−130 Xe isotopes.…”

Excited states and signature inversion inCs116

Excited states have been observed for the first time in the very neutron-deficient, odd-odd nucleus, 116 55 Cs 61 . The assignment to 116 Cs has been made by the detection of γ rays in coincidence with evaporated charged particles and with evaporation residues. The observed states form a rotational band which has been assigned to the ν(h 11/2 ) ⊗ π (h 11/2 ) configuration. Tentative spin assignments have been made on the basis of systematic comparisons with neighboring cesium isotopes. A low-spin signature inversion is observed in the band at a rotational frequency of about 0.23 MeV/h. The observed signature inversions in the odd-odd 116−126 Cs isotopes have been compared with the results of extended total Routhian surface calculations, in which signature inversion arises as a consequence of quadrupole-pairing correlations and triaxial deformation. As previously shown for some of the odd-odd A 120 isotopes, the calculations reproduce the signature inversions reasonably well.

“…In recent years, MχD * sgzhou@itp.ac.cn bands were indeed found in several nuclei [7][8][9][10][11]. The triaxiality may also play a role in the low-spin signature inversion [12][13][14][15][16][17]. Moreover, the development of triaxial shapes could lead to the termination of rotational bands in nuclei with A ≃ 110; see Ref.…”

Tetrahedral shapes of neutron-rich Zr isotopes from a multidimensionally constrained relativistic Hartree-Bogoliubov model

et al. 2017

We develop a multidimensionally constrained relativistic Hartree-Bogoliubov (MDC-RHB) model in which the pairing correlations are taken into account by making the Bogoliubov transformation. In this model, the nuclear shape is assumed to be invariant under the reversion of x and y axes; i.e., the intrinsic symmetry group is V4 and all shape degrees of freedom β λµ with even µ are included self-consistently. The RHB equation is solved in an axially deformed harmonic oscillator basis. A separable pairing force of finite range is adopted in the MDC-RHB model. The potential energy curves of neutron-rich even-even Zr isotopes are calculated with relativistic functionals DD-PC1 and PC-PK1 and possible tetrahedral shapes in the ground and isomeric states are investigated. The ground state shape of 110 Zr is predicted to be tetrahedral with both functionals and so is that of 112 Zr with the functional DD-PC1. The tetrahedral ground states are caused by large energy gaps around Z = 40 and N = 70 when β32 deformation is included. Although the inclusion of the β30 deformation can also reduce the energy around β20 = 0 and lead to minima with pear-like shapes for nuclei around 110 Zr, these minima are unstable due to their shallowness.
