摘要：
The lifetimes of low-lying states in the superdeformed (SD) bands of Hg-194 were measured by means of the recoil distance method using Gammasphere and the Cologne plunger device. The deduced transitional quadrupole moments in all three bands were found to be constant within the experimental uncertainties and equal those extracted from Doppler-shift attenuation method measurements for the higher-lying states, confirming that the decay out does not strongly affect the structure of the SD bands. The experimental findings are used to discuss the different mechanisms proposed for the decay out of SD bands.
