Lifetimes of a superdeformed band in {sup 82}Sr were measured with the centroid shift method. The measured average quadrupole moment of this band corresponds to a quadrupole deformation of {beta}{sub 2}{approx}0.49, which is slightly smaller than both the theoretical prediction, and the measured deformation of the SD band in the neighboring isotone {sup 84}Zr. Lifetimes of high spin states of three normally deformed rotational bands in {sup 82}Sr 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. {copyright} {ital 1998} {ital The American Physical Society}
