The lifetimes of three low-lying states in the superdeformed (SD) yrast band of {sup 194}Hg were measured applying the recoil-distance Doppler-shift method. As the deduced transition quadrupole moments Q{sub t} are equal within the experimental uncertainties to those extracted from a Doppler-shift attenuation method (DSAM) measurement for the high-lying states of the band, the assumption that the decay out of SD bands does not strongly affect the structure of the corresponding states is corroborated. By a simple mixing model, the decay can be described assuming a very small admixture of normal-deformed (ND) states to the decaying SD states. The deduced ND mixing amplitudes for the yrast SD bands in {sup 192,194}Hg and {sup 194}Pb are presented along with average transition quadrupole moments for the lower parts of the excited SD bands in {sup 194}Hg. {copyright} {ital 1997} {ital The American Physical Society}
