Description of the turnover of the dynamical moment of inertia of the superdeformed nuclear state

We propose in this paper an approach to describe the dynamical moment of inertia of superdeformed nuclear states in the spirit of variable moments of inertia. Both the general changing feature and the turnover of dynamical moments of inertia with rotational frequency are well described in our approach. It indicates that the competition between the angular momentum driving effect and the restraining effect plays a crucial role in determining the dynamical moments of inertia of superdeformed nuclear states.Physics, NuclearPhysics, Particles & FieldsSCI(E)16ARTICLE1117-1242
