Abstract

We have studied the density distribution in some “bubble” nuclei. The bubble nuclei are characterized by the depletion of nucleonic density at the center of the nucleus. We have explored the effect of nuclear deformation on proton bubble structure in the Si isotopic chain. The Covariant Density Functional Theory (CDFT) with density-dependent meson-exchange (DD-ME2) interaction has been employed. Triaxially constrained calculations are performed to investigate the deformed bubble structure. Deformation causes the mixing of shells hence reducing the bubble effect in the nuclei. The role of nuclear deformation in nuclear density profiles is explored and compared with the spherical limits.
