Quasicontinuous decay and properties of superdeformed excitations in Pb195

Superdeformed excitations in Pb-195 were populated via the Yb-174(Mg-26,5n) reaction, and gamma-ray spectroscopy measurements were made with Gammasphere. Analysis of the intensities of the discrete transitions between superdeformed states indicates that the decay out occurs from the favored band of the lowest signature pair. The quasicontinuous spectra associated with the decay of superdeformed bands in Pb-195 have been extracted for both signatures. The onset of gamma-ray intensity and the normalized gamma-ray intensity of the quasicontinuum decay spectrum are used to set a lower bound of 2.5 MeV at similar to 11h for superdeformed excitation energy relative to normal deformed excitations in Pb-195.
