Lifetimes of a superdeformed band in 82Sr were measured with the centroid shift method. The measured average quadrupole moment of this band corresponds to a quadrupole deformation of β2≈0.49, which is slightly smaller than both the theoretical prediction, and the measured deformation of the SD band in the neighboring isotone 84Zr. Lifetimes of high spin states of three normally deformed rotational bands in 82Sr were also measured with the Doppler shift attenuation method technique. The quadrupole moments of these normally deformed bands show a decrease at the highest spins, supporting the predicted band terminations.
