The influence of intruder states in even-even Po isotopes [PDF]

open access: yes, 2015
We study the role of intruder states and shape coexistence in the even-even $^{190-206}$Po isotopes, through an interacting boson model with configuration mixing calculation. We analyzed the results in the light of known systematics on various observable
