“…This fact could affect significantly the spectrum predicted by 5DCH calculations since the absence of particle number restoration leads to spurious mixing of solutions with different number of particles [37,38]. Finally, recent calculations have been reported in this region within the interacting boson model (IBM) framework [11,12]. Here the IBM hamiltonian of each isotope is mapped to the HFB potential energy surface in the (β 2 , γ) plane calculated with the Gogny D1M interaction [39].…”

“…In addition, the experiments suggest that the shape transition occurs from an oblate 72 Kr to prolate 74−76 Kr ground states, although, based on recent Coulomb excitation measurements, a prolate character of the 2 + 1 state in 72 Kr have been proposed [10]. On the other hand, the onset of deformation in the neutron rich isotopes around the region A ∼ 100 is the subject of recent studies [11,12]. Hence, while for Sr and Zr isotopes a quite sharp transition from spherical to deformed configurations in N = 58 − 60 is observed, the neutron rich Kr isotopes do not show such a rapid change.…”

“…Additionally, there are several methods based on selfconsistent underlying mean fields that have been applied to compute spectroscopic properties. Recently, a version of the Interacting Boson Model (IBM) has been used to study the shape dynamics of neutron rich Kr isotopes [12]. In this case, the parameters of the IBM hamiltonian are found by mapping the mean field energy surfaces obtained with the Gogny D1M interaction to the corresponding IBM ones.…”

Shape transitions and shape coexistence in the 70−98 Kr region are studied in a unified view with state-of-the-art beyond self-consistent mean field methods based on the Gogny D1S interaction. Beyond mean field effects are taken into account through the exact angular momentum and particle number restoration and the possibility of axial and non-axial shape mixing. The results of the low-lying properties of these isotopes are in good agreement with the experimental data when the triaxial degree of freedom is included. Shape transitions from axial-oblate ( 70−72 Kr) to triaxialprolate ( 74−78 Kr) and from spherical-triaxial ( 86−92 Kr) to axial-oblate ( 94−98 Kr) ground states are obtained. Additionally, low-lying 0 + excited states and quasi-gamma bands are found showing the richness of the collective structure in this region.

“…Many experimental data of nuclei in the isotopic (or isotonic) chain have been compared with the IBM calculations (for recent works, see Refs. [10,11,12,13]). The prediction of the geometric type of nuclei with the corresponding potential energy surface (PES) of the IBM model is also favorite subject as seen recently work in Refs.…”

We investigate even-even nuclei in the A ∼ 70 mass region within the framework of the proton-neutron quasi-particle random phase approximation (pn-QRPA) and the interacting boson model-1 (IBM-1). Our work includes calculation of the energy spectra and the potential energy surfaces V(β, γ) of Zn, Ge, Se, Kr and Sr nuclei with the same proton and neutron number, N = Z. The parametrization of the IBM-1 Hamiltonian was performed for the calculation of the energy levels in the ground state bands. Geometric shape of the nuclei was predicted by plotting the potential energy surfaces V(β, γ) obtained from the IBM-1 Hamiltonian in the classical limit. The pn-QRPA model was later used to compute half-lives of the neutron-deficient nuclei which were found to be in very good agreement with the measured ones. The pn-QRPA model was also used to calculate the Gamow-Teller strength distributions and was found to be in decent agreement with the measured data. We further calculate the electron capture and positron decay rates for these N = Z waiting point (WP) nuclei in the stellar environment employing the pn-QRPA model. For the rp-process conditions, our total weak rates are within a factor two compared with the Skyrme HF+BCS+QRPA calculation. All calculated electron capture rates are comparable to the competing positron decay rates under rp-process conditions. Our study confirms the finding that electron capture rates form an integral part of the weak rates under rp-process conditions and should not be neglected in the nuclear network calculations.

Relativistic Coulomb excitation of 88KrMoschner, K.; Blazhev, A.; Jolie, J.; Warr, N.; Boutachkov, P.; Bednarczyk, P.; Sieja, K.; Algora, A.; Ameil, F.; Bentley, M. A.; Brambilla, S.; Braun, N.; Camera, F. To investigate the systematics of mixed-symmetry states in N = 52 isotones, a relativistic Coulomb excitation experiment was performed during the PreSPEC campaign at the GSI Helmholtzzentrum für Schwerionenforschung to determine E2 transition strengths to 2 + states of the radioactive nucleus 88 Kr. Absolute transition rates could be measured towards the first and third 2 + states. For the latter a mixed-symmetry character is suggested on the basis of the indication for a strong M1 transition to the fully symmetric 2 1 + state, extending the knowledge of the N = 52 isotones below Z = 40. A comparison with the proton-neutron interacting boson model and shell-model predictions is made and supports the assignment.
