Nuclear structure of $$^{181}$$Au studied via $$\upbeta ^+$$/EC decay of $$^{181}$$Hg at ISOLDE

The /EC decay of mass separated samples of Hg was studied employing the TATRA spectrometer at the ISOLDE facility at CERN. The decay scheme was constructed for the first time. A Broad Energy Germanium detector was used to achieve this by combination of high-gain -ray singles spectroscopy and – coincidences. The systematics of excited states associated with the 1 proton-hole configuration in odd-Au isotopes was extended.
