Popis:	The superdeformed band in [sup 196]Pb has been studied extensively using the reaction [sup 170]Er([sup 30]Si,4[ital n]) at beam energies of 142, 146, and 151 MeV. New transitions have been added at the top and bottom of the previously known band. Gamma-ray directionsl correlations were measured for most of the transitions in the band verifying the expected stretched [ital E]2 character. The collectivity of the band has been measured using the Doppler shift attenuation method yielding an intrinsic quadrupole moment [ital Q][sub 0] of 18.3[plus minus]3.0 [ital e] b, in good agreement with theoretical predictions. The variations of the dynamic moment of inertia [ital scrI][sup (2)] as a function of the rotational frequency [h bar][omega] have been studied and compared with cranked shell model calculations. The dependence of [ital scrI][sup (2)] on mass for superdeformed bands in the Pb isotopes is also investigated.
