Quantum and Coulomb repulsion effects on the bubble structures in $^{204, 206}$Hg
Abstract
The decreasing proton and charge densities from around 5.0 fm towards the center of Hg are investigated by a covariant density functional theory at the beyond mean-field level.The charge-density difference between Pb and Hg is improved significantly and a central depression is still visible in the ground-state density of Hg when the dynamic correlations associated with symmetry restoration and shape mixing are taken into account. For the and excited states of Hg, their densities remain decreasing from 5.0 fm to around 2.0 fm, but become flat in the interior region. The results show that the bubble structure in Hg within 2.0 fm is mainly attributed to the quantum effect, while that beyond 2.0 fm is formed by the Coulomb repulsion.
