摘要: Recent self-consistent mean-field calculations predict a substantial depletion of the proton density in interior ${}^{34}\text{Si}$. In present study, we investigate how correlations beyond mean field modify this finding. The framework calculation is particle-number and angular-momentum projected generator coordinate method based on Hartree-Fock-Bogoliubov+Lipkin-Nogami states with axial quadrupole deformation. parametrization SLy4 Skyrme energy functional used together density-dependent pairing functional. For first time, applied to charge densities. impact correlations, symmetry restorations shape mixing profile analyzed step by step. All these effects significantly alter radial profile, tend bring it closer Fermi-type distribution.
