dc.description.abstractWe re-examine the nuclear structure properties of waiting point nuclei around A similar to 70 using the interacting boson model-1 (IBM-1) and the relativistic mean field (RMF) model. Effective density-dependent meson-exchange functional (DD-ME2) and density-dependent point-coupling functional (DD-PC1) were used for the RMF calculations. We calculated the energy levels, the geometric shapes, binding and separation energies of nucleons and quadrupole deformation parameters (beta 2). The shape co-existence phenomena in A similar to 70 nuclei (Se-68, Se-70, Br-70, Kr-70, Kr-72, Kr-74, Rb-74 and Sr-74) was later investigated. Spherical and deformed shapes of the selected waiting point nuclei were computed using the IBM-1 and RMF models, respectively. The proton-neutron quasiparticle random phase approximation (pn-QRPA) model was used to calculate beta-decay properties (Gamow-Teller strength distributions, beta-decay half-lives and branching ratios) of selected nuclei as a function of beta 2. The results revealed a significant variation in calculated half-lives and Gamow-Teller strength distributions as the shape parameter was changed. The beta 2 computed via DD-ME2 functional resulted in half-lives in best agreement with the measured data.
