A new superdeformed band with an intensity [similar to]5% relative to the yrast superdeformed band has been observed in [sup 194]Pb. Evidence for a second new band corresponding to the signature partner is also presented. These bands were observed with GAMMASPHERE early implementation via the [sup 174]Yb([sup 25]Mg, 5[ital n]) reaction at a beam energy of 130 MeV. The rotational characteristics of the new bands suggest an interpretation involving particle-hole excitations in the doubly-magic [sup 194]Pb superdeformed core. The results are compared to neighboring nuclei and recent theoretical calculations, and possible configurations are suggested.
