RADIOACTIVE DECAYS OF Au$sup 194$, Au$sup 196$, AND Au$sup 19$$sup 8$
The de-excitations of the 2+ second excited states of Pt/sup 194/ and Pt/ sup 196/ have been studied to compare crossover transition intensities to the 0+ ground states relative to the known cascade transitions to the 2+ first excited states. An intermediate-image beta-ray spectrometer was used to measure the internal-conversion electron spectra occurring in the decay of Au/sup 194/ and Au/ sup 196/ line is found in the decay of Au/sup 194/ corresponding to n O.618-Mev crossover having a transition intensity of 25% relative to the 0.290Mev cascade, provided the latter is assumed to be E2. In possible crossover transition compared with the 0.331Mev cascade. Au/sup 194/ exhihits the internal-conversion lines of 36 gamma-ray transitions which fit energetically into a proposed energy level seheme for Pt/sup 194/. A search in the electron spectrum of Au/sup 198/ showed no gamma-ray transitions other than the three already known. (auth)
