Description
A new superdeformed band with an intensity ∼5% relative to the yrast superdeformed band has been observed in 194Pb. Evidence for a second new band corresponding to the signature partner is also presented. These bands were observed with GAMMASPHERE early implementation via the 174Yb(25Mg, 5n) 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 194Pb superdeformed core. The results are compared to neighboring nuclei and recent theoretical calculations, and possible configurations are suggested
