Abstract

The first observation of the extremely neutrondeficient nucleus172Au is reported, produced using the fusion evaporation reaction70Ge+106Cd→176Hg* (Ex≃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 of172Au 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 ofb p ≤ 2 %.
