It is impossible to determine spins for superdeformed bands by fitting the [gamma]-transition energies alone. It is necessary to introduce a model. By using a variable moment of inertia (VMI) model one can estimate spins but cannot rule out the possibility of a [plus minus][h bar] uncertainty. Therefore, no objective evidence exists requiring the presence of quantized spin alignment in superdeformed nuclei. An alternative hypothesis that all superdeformed nuclei in a given mass region have the same VMI core, and thus essentially no alignment until high-[ital N] Coriolis effects become significant, seems to explain the present data.
