摘要：

The EUROGAM array has been used to investigate the decay out of the yrast superdeformed (SD) band in Pb-194. Six single step decays from the lowest observed SD slates to low-lying states at normal deformation (ND) have been identified. From this observation, the excitation energy of the SD band in Pb-194 is established at 4877 +/- 1.5 keV for the 6(+) SD state. The most probable spins and parities of all members of the SD band are also deduced assuming that the SD states have even spin and positive parity.
