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

The $$\\upbeta ^+$$\n /EC decay of mass separated samples of $$^{181}$$\n 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 $$\\upgamma $$\n -ray singles spectroscopy and $$\\upgamma $$\n –\n $$\\upgamma $$\n  coincidences. The systematics of excited states associated with the 1\n $$h_{11/2}$$\n proton-hole configuration in odd-Au isotopes was extended.
