Abstract

The quasi-continuum of γ rays from the feeding and decay of superdeformed and normal bands in the nucleus ¹⁵²Dy have been extracted in 1 - and 2 - dimensional spectra. The E_γ-E _γ correlations in the latter reveals strong ridges associated with superdeformed and normal states in this nucleus. The entry distributions for normal and superdeformed bands were also extracted. A Monte Carlo model was developed that simultaneously describes all the quasi-continuum and ridge spectra as well as the feeding intensity of the superdeformed bands. Through the calculation of the continuum of γ rays at finite temperature, the rotational damping widths in the normal and superdeformed wells were extracted.
