Abstract
States up to ) have been established in the neutron-deficient nucleus by means of the Cr, 2pγ) reaction. At a rotational frequency ħω=0.30 MeV, the ground-state band is crossed by a band built on the aligned [π two-quasiproton configuration. This proton-aligned band was observed from spins to (). A second state was established which is most likely built on the [ν two-quasineutron configuration. The γ-vibrational band was observed up to ) with the odd- and even-spin members exhibiting a pronounced signature splitting. The results are compared to those found recently for the lighter and N=76 isotones.
