High-spin states in ${}^{123}\mathrm{Xe}$ were populated in $\mathrm{the}{\hspace{0.5em}}^{110}\mathrm{Pd}{(}^{18}\mathrm{O},5n)$ reaction at 75 MeV and gamma-ray coincidences were measured with the GASP spectrometer. A new rotational sequence of enhanced dipole transitions was established. This band, as well as a similar band $\mathrm{in}{\hspace{0.5em}}^{124}\mathrm{Xe},$ may be described within the framework of the tilted axis cranking model as bands for which comparable amounts of angular momentum are generated by magnetic and collective rotation, respectively.
