Possibility of deformed dual bubble-like structure in light nuclei

The nuclei with a depressed central nucleonic density (bubble nuclei) are studied. The relativistic Hartree-Bogoliubov model with density-dependent meson-exchange interaction has been used to explore the possibility of deformed dual bubble-like structures in light nuclei, which are experimentally accessible. In dual bubble nuclei, the central densities for both proton and neutron deplete simultaneously. The unoccupancy of low angular momentum states for proton and neutron orbitals plays a vital role in the formation of bubble structures. We find favorable candidates around N or/and Z = 14 exhibiting a deformed dual bubble-like structure.
