Abstract

High-spin states have been studied in 132Ce produced in the 100Mo(36S,4nγ) reaction using the EUROGAM II spectrometer. The structure of the normally deformed states (β2 ∼ 0.2) has been investigated. Eight ΔI = 2 bands and three ΔI = 1 bands have been identified and the level scheme extended up to spin and parity (40+) at an excitation energy 19.79 MeV. The results are interpreted with the aid of Woods-Saxon cranking calculations, which suggest a variety of triaxial (γ) shapes in this nucleus stabilised by specific active quasiparticle orbitals.
