Description
Excited states in 143Xe, populated in spontaneous fission of 248Cm, are studied by means of γ spectroscopy using the EUROGAM 2 Ge array. We identify three rotational bands in 143X: a decoupled band originating from the i13/2 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 143Xe is compared to quasiparticle-rotor model calculations, performed with a reflection-symmetric potential.
