Six superdeformed bands have been observed in [sup 193]Pb following the [sup 174]Yb([sup 24]Mg,5[ital n]) reaction at a beam energy of 131 MeV. The in-beam [gamma] rays were detected with GAMMASPHERE early implementation. Two of the bands have dynamic moments of inertia which have an anomalously low increase with rotational frequency, and are interpreted as the favored and unfavored signature components of the [ital N]=7 neutron orbital. The other four bands have increasing dynamic moments of inertia typical of superdeformed bands in the [ital A]=190 region, and are interpreted as two pairs of signature partner bands based on high-[ital K] quasineutron excitations. The effects of the intruder [ital N]=7 neutron orbital on the superdeformed rotational characteristics are discussed.
