Abstract: The decay of 123Ba to 123Cs has been studied with mass-separated sources. Singles spectra of -rays, X-rays and conversion electrons as well as , , and X-e-t coincidences were recorded. A level scheme of 123Cs has been constructed including 26 new excited states and 82 transitions. The existence of a I =11/2-, T =1.7 s isomer, bandhead of the h band, is confirmed. Its excitation energy equals 156.3 keV. A new T =114 ns isomer has been established at 232 keV using the in-beam recoil catcher technique. It is assigned to the I =9/2+ bandhead of the g band. Collective bands based on the 1/2+ ground state and first 3/2+ excited state are proposed. The level structure is described in the frame of the interacting boson-fermion and core-quasiparticle coupling models.
