Experimental observation of [Formula: see text]Si as a proton bubble nuclei has heated up the interest in the study of exotic bubble shaped nuclei. In this work, some of the potential doubly bubble-like (for proton as well as neutron both simultaneously) cases have been explored using relativistic Hartree–Bogoliubov (RHB) in light mass region, specially around N or [Formula: see text]. Further, the role of pairing and the evolution of new shell gaps around [Formula: see text] or [Formula: see text] and 34 have been investigated, as one moves toward drip lines. This study suggests that the occupancies/vacancies of neutron/proton orbitals for lower angular momentum state plays major role in nuclear structure to create bubble-like structure and [Formula: see text]O[Formula: see text], [Formula: see text]Mg8 and [Formula: see text]Si[Formula: see text] may have dual bubble-like structures.

Electron capture on nucleons and nuclei, is one of the most important weak interaction processes in the dynamics and evolution of massive stars. Especially on nuclei of the Fe mass region the role of e− capture is crucial in the phase of stellar core collapse. Furthermore, a realistic treatment of electron capture on heavy nuclei provides signi cant information in the hydrodynamics of core collapse and bounce. In this work, we exploit the advantages of a recently published numerical approach to perform nuclear structure calculations of the electron capture in F e group nuclear isotopes. As a rst concrete example, which is simultaneously o ering a good test of ourmethod,wechoosethereaction56Fe(e−,νe)56Mn* that plays a decisive role in core collapse supernovae. We also improve the previous formalism by constructing compact analytical expressions for the required reduced matrix elements of all basic multipole operators in isospin representation. Such a compact formalism o ers the advantage of performing state-by-state calculations of the transition rates for semi- leptonic nuclear processes through advantageous computer codes written in isospin representation.

Large scale nuclear structure studies within the complex Excited Vampir model involving rather large single particle basis systems as well as general two-body interactions are used to investigate exotic phenomena in medium mass nuclei. Results are presented on the influence of Coulomb induced isospin-mixing on the superallowed Fermi β decay in isovector triplets of nuclei, as well as the mechanism responsible for the generation of magnetic bands in the A ≃ 80 mass region.

The well-known Grodzins product [Formula: see text]2, 0[Formula: see text]2[Formula: see text] constancy rule was generalized to the Grodzins linearity relation in our recent work in the form of [Formula: see text] versus [Formula: see text] linear plots. In this form, besides testing the linear relation of [Formula: see text]) and kinetic moment of inertia, it also served as a tool for the study of the spectral details of the nuclei, and for the study of the variation of nuclear structure with [Formula: see text] and [Formula: see text] We now study its extension to the intra band [Formula: see text]2 transition from the higher spins of the ground bands of even [Formula: see text] even [Formula: see text] nuclei of the mid-mass region of Xe–Pt chain of isotopes. We use the plots of [Formula: see text]2, [Formula: see text] versus [Formula: see text] [Formula: see text] and 6[Formula: see text] to test their linear relationship. There seems to be a good correlation of the two entities even at the higher spins for all the nuclei studied here. The deviations from linearity in specific cases can be used for studying the nuclear structures involved.
