Abstract
Excited states in the neutron-deficient odd-odd proton-unbound nuclide have been investigated in two separate experiments. In the first experiment, nuclei were produced in the reactions of 380 MeV ions with an isotopically enriched target. The -decay chain of the state in was analyzed. Fine structure in the decay of the state in established a 66 keV difference in excitation energy between the lowest-lying and states in . Higher-lying states in were populated in the reactions of 255 MeV ions with an isotopically enriched target. Gamma-ray decay paths that populate, depopulate, and bypass a isomeric state have been identified. The general features of the deduced level scheme are discussed and the prospects for observing proton emission branches from excited states are considered.
