✦ Synopsis

The nucleus 124 Cs has been studied by in-beam γand e --spectroscopy techniques with the fusion-evaporation reaction 115 In( 12 C, 3nγ) at 57 MeV. Multipolarities of the main low-energy transitions have been deduced from electron spectra. A level scheme is proposed with firm I π assignments. Low-spin low-lying levels and high-spin states have been investigated. The low-spin levels and two-quasiparticle bands are interpreted by using the interacting boson-fermion-fermion model. The band structures are also discussed in the frame of the cranked-shell model.
