Abstract

New spectroscopic results for high-spin states in ¹⁹²Os populated in deep-inelastic reactions include the identification of a 2-ns, 12⁺ isomeric state at 2865 keV and a 295-ns, 20⁺ state at 4580 keV and their associated δJ=2 sequences. The structures are interpreted as manifestations of maximal rotation alignment within the neutron i_13/2 and proton h_11/2 shells at oblate deformation. Rotational band members based on the long-lived, K^π=10^- isomer are also identified for the first time. Configuration-constrained, potential-energy-surface calculations predict that other prolate multi-quasiparticle high-K states should exist at low energy.
