AN ALLEGED DISTORTED ROTATION

The Giant Angle Dipole model describes a contrarotational (scissors) m otion with superimposed deformation distortions. They cause changes in the mass and stiffness parameters and the physical observables (excit ation energies and transition probabilities) corresponding to undistor ted scissors motion. It is shown here that the observables, derived in this model using normalized excited states; coincide with the predict ions for the low- and high-frequency modes with Delta N = 0 and 2, obt ained by a recent canonical quantization of the isovector rotor, where no deformation distortions are assumed.
