The Ta-155 nuclei were populated through the alpha decay of Re-159, which has been observed for the first time. The (159)Rc nuclei were produced in reactions of 300 MeV Ni-58 ions with an isotopically enriched Cd-106 target, separated in-flight using the RITU separator and implanted into the GREAT spectrometer. The Re-159 a decay emanates from the proton-emitting pi h(11/2) state and populates a state in Ta-155 which decays by the emission of a proton from a pi h(11/2) orbital. The results fit in with the systematics of proton and alpha-particle separation energies in the region, but disagree with the previously reported decay properties of Ta-155.eninfo:eu-repo/semantics/closedAccessRADIOACTIVITY Re-159(alpha)[from Cd-106(Ni-58,p4n)]Ta-155(p)[from Re-159 a decay]measured E-alpha, E-p, T-1/2branching ratio.
