The superdeformed band in Pb196 has been studied extensively using the reaction Er170(30Si,4n) 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 E2 character. The collectivity of the band has been measured using the Doppler shift attenuation method yielding an intrinsic quadrupole moment Q0 of 18.3±3.0 e b, in good agreement with theoretical predictions. The variations of the dynamic moment of inertia scrI(2) as a function of the rotational frequency Latin small letter h with strokeω have been studied and compared with cranked shell model calculations. The dependence of scrI(2) on mass for superdeformed bands in the Pb isotopes is also investigated.
