B(E2) TRANSITION-PROBABILITIES IN THE Q-ROTATOR MODEL WITH SUQ(2) SYMMETRY

The SU(q)(2) symmetry of the q-rotator model, which for rotational bands predicts squeezing of the energy levels equivalent to the variable moment of inertia (VMI) model, predicts an increase with angular momentum of the B(E2) transition probabilities among these levels, while the rigid rotor model predicts saturation and the interacting boson model (IBM) predicts a decrease. Some evidence supporting the SU(q)(2) prediction is presented. The possible usefulness of the quantum algebraic method in extending the VMI concept to B(E2) transition probabilities is pointed out.
