Abstract
The nucleus Cs-124 has been studied by in-beam gamma- and e(-)-spectroscopy techniques with the fusion-evaporation reaction In-115(C-12,3n gamma) at 5 7 MeV. Multipolarities of the main low-energy transitions have been deduced from electron spectra. A level scheme is proposed with firm I-pi assignmen ts. Low-spin low-lying levels and high-spin states have been investigated. The low-spin levels and two-quasiparticle bands are interpreted by using th e interacting boson-fermion-fermion model. The band structures are also dis cussed in the frame of the cranked-shell model. (C) 2001 Elsevier Science B .V. All rights reserved.
