New signature of a first order phase transition at the O(6) limit of the IBM
Shape invariants within the interacting boson model are used to describe the ? deformation of the ground state and 02+ state along the ?-rigid leg of the extended Casten triangle between the symmetry limits SU(3) and SU(3)? via the O(6) limit. Similarly to the recently discovered ?-deformation crossing of the ground state with the 02+ state between the symmetry limits U(5) and SU(3), a crossing of those states with respect to the ? deformation is observed between SU(3) and SU(3)?. The newly...[Show more]
