Excited states in the neutron-deficient odd-odd proton-unbound nuclide Ta158 have been investigated in two separate experiments. In the first experiment, Ir166 nuclei were produced in the reactions of 380 MeV Kr78 ions with an isotopically enriched Mo92 target. The α-decay chain of the 9+ state in Ir166 was analyzed. Fine structure in the α decay of the 9+ state in Re162 established a 66 keV difference in excitation energy between the lowest-lying 9+ and 10+ states in Ta158. Higher-lying states in Ta158 were populated in the reactions of 255 MeV Ni58 ions with an isotopically enriched Pd102 target. Gamma-ray decay paths that populate, depopulate, and bypass a 19- 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.
