Abstract

WOS: 000240847400007, The observation of the new nuclide Re-159(75)84 provides important insights into the evolution of single-particle structure and the mass surface in heavy nuclei beyond the proton drip line. This nuclide, 26 neutrons away from the nearest stable rhenium isotope, was synthesised in the reaction Cd-106(Ni-58, p4n) and identified via its proton radioactivity using the RITU gas-filled separator and the GREAT focal-plane spectrometer. Comparisons of the measured proton energy (E-p = 1805 +/- 20 keV) and decay half-life (t(1/2) = 21 +/- 4 mu s) with values calculated using the WKB method indicate that the proton is emitted from an h(11/2) state. The implications of these results for future experimental investigations into even more proton unbound nuclei using in-flight separation techniques are considered. (c) 2006 Elsevier B.V.

Abstract

International Conference on Proton Emitting Nuclei and Related Topics -- JUN 17-23, 2007 -- Lisbon, PORTUGAL, WOS: 000252267300021, 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., Fundacao Ciencia & Tecnol, Minist Ciencia & Tecnol, Fundacao Calouste Gulbenklan, Fundacao Luso Americana, UK Engineering and Physical Sciences Research Council; Swedish Natural Science Research Council; Academy of Finland under the Firmish Centre of Excellence Programme (project 44875 Nuclear and Condensed Matter Physics Programme at JYFL); European Union Sixth Framework contract EURONS [RII3-CT-2004-506065]; European Union Marie Curie Programme [HPMT-CT-2001-00250], The authors would like to thank the technical staff at the Accelerator Laboratory at the University of Jyvaskyla for their excellent support and to Paul Morrall from Daresbury Laboratory for making the targets.
