Shape Coexistence in Pb186: Beyond-mean-field description by configuration mixing of symmetry restored wave functions
arXiv:nucl-th/0212016 · doi:10.1016/S0370-2693(03)00330-7
Abstract
We study shape coexistence in Pb186 using configuration mixing of angular-momentum and particle-number projected self-consistent mean-field states. The same Skyrme interaction SLy6 is used everywhere in connection with a density-dependent zero-range pairing force. The model predicts coexisting spherical, prolate and oblate 0+ states at low energy.
