Low-lying levels and collective bands in doubly-odd $^{124}$Cs
Résumé
The nucleus 124 Cs has been studied by in-beam γ - and e − -spectroscopy techniques with the fusion–evaporation reaction 115 In( 12 C, 3n γ ) 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. (Elsevier)
