Dipole transitions linking signature partner superdeformed bands in [sup 193]Hg have been observed. Measurements of the photon decay branching ratios, taken together with the average superdeformed quadrupole moment measured in neighboring nuclei, enable the absolute [ital M]1 strengths to be determined. From these data, using the strong coupling model, we find ([ital g][sub [ital K]][minus][ital g][sub [ital R]])[ital K]/[ital Q][sub 0]=[minus]0.14[plus minus]0.01 ([ital e] b)[sup [minus]1], [ital g][sub [ital K]]=[minus]0.65[plus minus]0.14 with [Omega]=2.8[plus minus]0.8. These data are consistent with the superdeformed neutron orbital being [512]5/2[sup [minus]] as predicted by cranked Woods-Saxon calculations.
