Effects of Octupole Vibrations on Quasiparticle Modes of Excitation in   Superdeformed $^{193}$Hg
  A particle-vibration coupling calculation based on the RPA and the cranked shell model has been carried out for superdeformed rotational bands in $^{193}$Hg. The result suggests that properties of single-particle motions in superdeformed nuclei may be significantly affected by coupling effects with low-frequency octupole vibrational modes, especially by the lowest $K=2$ octupole mode.
