Abstract

High-spin states in 185Au have been populated via the 169Tm(20Ne, 4nγ) and 175Lu(16O, 6nγ) reactions. We observe two aligned bands built on rapidly downsloping h 9 2 and i 13 2 proton orbitals. This permits one to examine for the first time the role of these and other orbitals in backbending, free from deformation effects. The i 13 2 band is observed to backbend, as does the 184Pt core, but the h 9 2 band does not, thus providing strong evidence for the dominant role of h 9 2 protons to backbending in this nucleus. © 1978.
