β- and α-decay spectroscopy of 182Au
An alpha- and beta-decay study of a pure source of laser-ionized and mass-separated 182Au (Z = 79, N = 103) was carried out at the ISOLDE Decay Station at the ISOLDE-CERN facility. Detailed gamma-gamma analysis following EC/beta+ decay of 182Au was performed, and the level scheme of daughter nuclide...

| Sumario: | An alpha- and beta-decay study of a pure source of laser-ionized and mass-separated 182Au (Z = 79, N = 103) was carried out at the ISOLDE Decay Station at the ISOLDE-CERN facility. Detailed gamma-gamma analysis following EC/beta+ decay of 182Au was performed, and the level scheme of daughter nuclide 182Pt was considerably extended via the identification of 125 new levels and 336 new gamma-ray transitions. The nonexistence of a relatively long-lived isomeric state in 182Au and influence of the pandemonium effect on beta-decay feeding intensities are discussed. Differences in feeding for two coexisting bands in 182Pt were investigated. The alpha-decay scheme of 182Au was extended and an alpha-decay branching ratio of 0.129(11)% was measured. Hindrance factors for alpha-decay branches were calculated and I pi = (1+, 2+, 3+) assignment for the 178Ir ground state was proposed. |
