Four bands of enhanced dipole transitions, with weak crossovers, have been observed in ${}_{}{}^{193}{}_{}{}^{}\mathrm{Pb}$. Three of these bands are connected to the spherical levels. In addition, the spherical level scheme has been extended. The nuclear spectroscopy was done with the early implementation of GAMMASPHERE and HERA arrays of Ge detectors. The nucleus ${}_{}{}^{193}{}_{}{}^{}\mathrm{Pb}$ was populated in the ${}_{}{}^{174}{}_{}{}^{}\mathrm{Yb}$${(}^{24}$Mg,5n) reaction at beam energies of 129, 131, and 134 MeV. The experimental results are compared to tilted-axis cranking calculations. The systematical behavior of the dipole bands in the heavier odd-A Pb isotopes, ${}_{}{}^{195,197,199,201}{}_{}{}^{}\mathrm{Pb}$, is also discussed. © 1996 The American Physical Society.
