Abstract
A new superdeformed band with an intensity similar to 5% relative to t he yrast superdeformed band has been observed in Pb-194. Evidence for a second new band corresponding to the signature partner is also prese nted. These bands were observed with GAMMASPHERE early implementation via the Yb-174(Mg-25, 5n) reaction at a beam energy of 130 MeV. The ro tational characteristics of the new bands suggest an interpretation in volving particle-hole excitations in the doubly-magic Pb-194 superdefo rmed core. The results are compared to neighboring nuclei and recent t heoretical calculations, and possible configurations are suggested.
