    Probing single-particle structures beyond the proton drip line
    (AMER INST PHYSICS, 2007) Page, R. D.; Bianco, L.; Darby, I. G.; Joss, D. T.; Grahn, T.; Herzberg, R. -D.; Juutinen, S.; Ferreira, LS; Arumugam, P
    Single-particle energies have been investigated in the closed neutron shell proton emitter Ta-155. 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.
