SUQ(2) DESCRIPTION OF ROTATIONAL SPECTRA AND ITS RELATION TO THE VARIABLE MOMENT OF THE INERTIA MODEL

Rotational spectra of even-even nuclei can be described by the quantum algebra SU(q)(2). The two-parameter formula given by the algebra is equivalent to an expansion in terms of powers of j(j + 1), similar to the expansion given by the variable moment of inertia (VMI) model. The moment of inertia parameter in the two models, as well as the small parameter of the expansion, are found to have similar numerical values.
