Abstract
A phenomenological geometrical model is proposed to describe col- lective states in even-even nuclei with quadrupole and octupole deformation. The model is applied for a systematic description of the rotation-vibration dynamics associated with the alternate parity bands observed in the isotopic chains of Ra, Th, U, and Pu nuclei. As a result, the A = 224–228 mass region of the Ra and Th nuclei was identified as critical for the transition between dynamic and static octupole deformation, which commences at different spins. The model also predicts a specific spin dependence for the transition probabilities in these critical nuclei.
