摘要：

The yrast superdeformed (SD) structure of Pb-194 has been studied using the EUROGAM gamma-ray spectrometer. New results have been obtained at low as well as at high spin values. At low frequency, the SD band has been extended to the lowest-spin SD state ever observed in the A similar to 190 region. The energies of Pb-194 and Hg-192 SD bands are identical for ($) over bar h omega < 0.25 MeV. However, they diverge for higher frequency, which rules out the idea that these two SD bands are identical. Moreover, the SD band of Pb-194 is populated at lower spin values than that of Hg-192 and de-excites towards normally-deformed (ND) states at a spin value lower than that of Hg-192. This suggests that the barrier separating the SD and ND minima in the potential energy surface is higher in Pb-194 than in Hg-192.
