Excited states in Xe-143, populated in spontaneous fission of Cm-248, are studied by means of gamma spectroscopy using the EUROGAM 2 Ge array. We identify three rotational bands in X-143: a decoupled band originating from the i(13/2) neutron excitation, a strongly coupled band based on the 5/2 ground state, and a decoupled band based on the 322.9-keV level with spin 9/2. The new excitation scheme of Xe-143 is compared to quasiparticle-rotor model calculations, performed with a reflection-symmetric potential.
