Excited states of the nucleus 123Xe have been investigated with the fusion-evaporation-reaction 110Pd(18O,5n)123Xe at 86 MeV beam energy, using the compton-suppressed NORDBALL-multidetector-system at the Niels-Bohr-Institute in Risø, Denmark. The level scheme of 123Xe was extended up to a level of tentative $53/2^+\hbar$. Four excited bands of 3-quasiparticle-character were observed. Analyzing the directional correlation information, we could assign spin- and parity-values to all observed bands in 123Xe. The observed band structures fit well into systematics of the neighboring nuclei 125Xe and 127Xe.
