Weak γ rays from the electron-capture decay of194Au

Abstract

We present \ensuremath{\gamma}-ray energies and intensities of 34 new weak transitions in the electron-capture decay of ${}^{194}\mathrm{Au}.$ These \ensuremath{\gamma} rays were detected in singles experiments with high-purity Ge and anti-Compton detectors, and in \ensuremath{\gamma}-\ensuremath{\gamma} coincidence experiments, with the HERA array of Ge detectors. Their placements in the decay scheme confirm levels in ${}^{194}\mathrm{Pt}$ at 1373.9 and 1737.3 keV observed in the electron-capture decay of ${}^{194}\mathrm{Au}.$
