The influence of intruder states in even-even Po isotopes

Book Contribution - Book Chapter Conference Contribution

We study the role of intruder states and shape coexistence in the even-even Po190-206 isotopes, through an interacting boson model with configuration mixing calculation. We analyzed the results in the light of known systematics on various observable in the Pb region, paying special attention to the unperturbed energy systematics and quadrupole deformation. We find that shape coexistence in the Po isotopes behaves in very much the same way as in the Pt isotopes, i. e., it is somehow hidden, contrary to the situation in the Pb and the Hg isotopes.
