The deviation of nuclear rotational spectra from simple rotational pattern of a symmetric top is explained in the framework of the cranking model with pair correlations which change with angular velocity. To determine changes in the energy gap with angular momentum, we use a variational method used by Bardeen and treat the gap as a free parameter, chosen to make the energy in the rotating frame a minimum. The results obtained by the present model agree quite well with the experimental data for rare-earth nuclei. The critical spin corresponding to the vanishing gap is found to be about 30-40 in this region.
