ResumenThe neutron-deficient nucleus 66Ge was populated at high spin in two experiments using the reaction 40Ca(32S, α2p) at beam energies of 105 and 95 MeV. In the first experiment, a self-supporting 40Ca target was used, while a gold-backed target of similar thickness was used in the second experiment, γ rays were detected with the EUROBALL array, combined with the charged-particle detector array EUCLIDES and the Neutron Wall. The level scheme of 66Ge was extended up to E ≈ 18 MeV and Iπ = (23-). Above angular momentum 10+, we found two sequences, connected by energetically staggered ΔI = 1 M 1 transitions. The total Routhian surface calculations describe 66Ge at lower spins as a γ-soft nucleus having a moderate deformation of β2 ≈ 0.23, while a triaxial deformation is predicted for the band structures above Iπ = 10+. To our knowledge, this is the first observation of staggered Ml transitions in a deformed four-quasiparticle π(g9/2 2) ν(g9/2 2) structure. ©2003 American Physical Society
