Abstract

The yrast superdeformed band in [Formula Presented]Pb has been populated using the [Formula Presented]Yb[Formula Presented]Mg,5n)[Formula Presented]Pb reaction at [Formula Presented] MeV. Decay [Formula Presented] rays were detected using the GAMMASPHERE array at the 88-Inch Cyclotron. Twelve [Formula Presented]-ray transitions have been observed directly linking three members of the [Formula Presented]Pb yrast superdeformed band to low-lying normal deformed levels. Anisotropy measurements indicate that these linking decays include [Formula Presented]1, [Formula Presented]1, and mixed [Formula Presented] multipolarities. The radiative widths deduced are very inhibited, typically [Formula Presented] Weisskopf units (W.u.) and [Formula Presented] W.u. Without recourse to a priori assumptions [Formula Presented] and [Formula Presented] keV have been unambiguously assigned to the lowest-lying observed superdeformed state (the state populated by the 170-keV intraband transition). The intensity of the observed primaries accounts for 21(2)% of the superdeformed band population.
