Abstract

The quasicontinuum of \ensuremath{\gamma} rays from the feeding and decay of superdeformed and normal bands in $^{152}\mathrm{Dy}$ have been extracted in one- and two-dimensional spectra. The ${E}_{\ensuremath{\gamma}}\text{\ensuremath{-}}{E}_{\ensuremath{\gamma}}$ correlations in the latter reveal strong ridges associated with superdeformed and normal states in this nucleus. The entry distributions for normal and superdeformed bands have been extracted from measured fold and sum-energy distributions. A Monte Carlo model was developed to simultaneously describe all the quasicontinuum and ridge spectra as well as the feeding intensity of the superdeformed bands. The rotational damping widths in the normal and superdeformed wells were derived based on a comparison of the data with model calculations of the continuum of \ensuremath{\gamma} rays at finite temperature.
