- Title
Superfluid-to-Normal Phase Transition in Superdeformed Bands.
- Authors
Pavlichenkov, I. M.
- Abstract
A semiclassically exact solution for the second inertial parameter β is found for the superfluid and normal phases. An interpolation between these limiting values shows that β changes sign in the transition region at the spin I[sub c] that is critical for the rotational spectrum. A superfluid-to-normal transition reveals itself in a specific variation of β versus the spin I. Experimental data show the existence of a transition for superdeformed bands in the A ∼ 80,130, and 150 mass regions and for some bands characterized by a normal deformation. A transition to the normal phase explains the extreme regularity of superdeformed bands.
