The first observation of the extremely neutrondeficient nucleusAu is reported, produced using the fusion evaporation reactionGe+Cd→Hg (E≃64 MeV). Mass separated evaporation residues were implanted into a double-sided silicon strip detector, and the energy and time of subsequent decay events were recorded. The alpha decay ofAu was measured with an energy =6860±10 KeV, corresponding to =7020±10 Kev, and a half-life of 4±1 ms. No evidence was seen for a proton decay branch, implying a limit of b≤ 2 %.
