Two weakly populated rotational bands with energy spacings characteristic of superdeformation (SD) have been found in the W-186(O-18,xn) reaction at a beam energy of E = 113 MeV. One of the bands corresponds to the known sequence in 196Pb, the other to an extremely weak cascade previously assigned to 198Pb. Both bands have been extended to higher frequency. The behavior of the dynamic moments of inertia for the known SD bands in the Pb nuclei are discussed. Deformation and pairing self-consistent cranked Woods-Saxon calculations of the T(2) moments of inertia for bands in the even-even isotopes Pb-194-Pb-198 are presented.
