Possible dual bubble-like structure predicted by the relativistic Hartree-Bogoliubov model
(2020) In International Journal of Modern Physics E- Abstract
Experimental observation of 34Si 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 Z = 14. Further, the role of pairing and the evolution of new shell gaps around N or Z = 32 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 822O14, 1220Mg8 and 1448Si34 may have dual bubble-like...
