“…It was found that the inclusion of correction energies from both symmetry restoration and shape fluctuation can either improve (D1M) or worsen (D1S) the description of nuclear binding energies, depending on how the parameters of the forces are parameterized. A recent study based on the CDFT [76] has shown clearly that the inclusion of the rotational correction energy is essential to achieve a better description of nuclear masses with the PC-PK1 force, even though the rotational correction energy was estimated approximately with the cranking approximation.…”

“…As a result, the PGCM calculation allowing the mixing of only axially deformed states predicts the coexistence of a weakly oblate deformed ground-state band with a prolate prolate excited band. Figure 9 displays the low-lying spectra of 76 Kr from the PGCM calculation by mixing axially deformed only or also triaxially deformed configurations, in comparison with data. It is shown that a restriction to axial states fails to reproduce the low-energy structures of the spectrum (including both excitation energies and electric quadrupole transitions), demonstrating the important role of the triaxially deformed configurations in the low-lying states of 76 Kr.…”

Symmetry techniques based on group theory play a prominent role in the analysis of nuclear phenomena, and in particular in the understanding of observed regular patterns in nuclear spectra and selection rules for electromagnetic transitions. A variety of symmetry-based nuclear models have been developed in nuclear physics, providing efficient tools of choice to interpret nuclear spectroscopic data. This chapter provides a pedagogical introduction to the basic idea of symmetrybreaking mechanism and symmetry-restoration methods in modeling atomic nuclei.

“…Since the last-bound isotopes in DRHBc calculations are magic nuclei at N = 184, the neutron drip lines of Hf, W, Os, Pt, and Hg isotopes in RCHB and in DRHBc are the same. For an extensive summary of nuclear properties including the isotopes discussed in this work, we refer to [68].…”

The shape of a nucleus is one of fundamental nuclear properties. We perform a systematic investigation of bubble nuclei that also exhibit shape coexistence in Hf, W, Os, Pt and Hg even-even isotopes using the deformed relativistic Hartree-Bogoliubov theory in continuum. For a systematic study, we first consider nuclear bubble structures and shape coexistence separately. We confirm that deformations and pairing correlations hinder bubble structures by comparing our results with those from relativistic continuum Hartree-Bogoliubov theory that assumes spherical symmetry in nuclei. We then predict candidate isotopes with both bubble structure and shape coexistence. We observe that the depletion fraction factor that characterizes bubble structure is mostly smaller in oblate deformation than in prolate, while some isotopes such as 206 Os have bubble structures both in oblate and prolate deformations. We compare the proton single-particle energy levels for the candidates of shape coexistence both with only prolate bubble structure and with prolate and oblate bubble structures.
