Abstract
We study the effects of deformation, tensor and pairing correlation on the evolution of bubble structure in 46Ar, 22O and Cl isotopes using a deformed Skyrme-Hartree-Fock model with BCS and Lipkin-Nogami number projection approximation. The parameter SLy5 of the Skyrme energy functionals is adopted together with various kinds of density-dependent pairing interaction and various kinds of tensor interaction. In the spherical case, considering pairing correlation (IS + IV) or switch off pairing, there is a clear bubble structure in 46Ar with interaction SLy5 + Tw, respectively. For 46Ar, we find that deformation weakens the bubble structure strongly, and pairing correlation also weakens the bubble in 46Ar and 22O , respectively. On the other hand, the SLy5 + Tw + IS + IV interaction evolves the bubble structure of neutron-rich Cl isotopes 43-47Cl in deformed cases because the occupation probability of states $ 2s_{1/2}$ decreases from 1 to 0.5.
