On the Staggering Effect of Dynamical Moments of Inertia in Superdeformed Bands

Abstract

The possibility of the appearance of the C${}_4$ symmetry in the rotational bands is studied within the particle-rotor model. Allowing for a slight triaxiality of the rotor it is shown that the lowest states of the system for a sufficiently high spin possess the symmetry which allows to distinguish states differing by two units of angular momentum.
