Abstract
Lifetimes of superdeformed (SD) states in [sup 194]Pb were measured with the recoil distance Doppler shift method. The transition quadrupole moments were found to be constant in the whole SD band down to the lowest observed transition. The lifetime of the spin 10[r reversible] SD state is reduced as compared to the rotational value due to the [gamma] decay out of the band. This decay can be described by a very small admixture of normal deformed states to the spin 10[del]D state. The obtained lifetimes provide strong experimental evidence for the existence of the SD configuration down to very low spin states.
