191AU c 1971Be61: Source activity was produced by the {+197}Au(d,8n)
191AU2c reaction, E=80 MeV, target thickness=38 mg/cm{+2}. For conversion
191AU3c electron measurements, the mercury was evaporated by heating the gold

191AU5c copper rod. Iron-free beta-ray spectrometer, plastic scintillator,
191AU6c Ge(Li), Si(Li) with Be window. Measured E|g, I|g, conversion
191AU7c electrons, e-|g coin, |g-|g coin. Deduced level scheme, spin, parity,
191AU7c |g-ray multipolarity.
191AU c
191AU c 1975Zg01: Source was produced primarily through the decay of
191AU2c {+191}Tl, which was obtained via the {+181}Ta({+16}O,6n) reaction.
191AU3c Measured E|g, conversion electrons, |g|g-coin, |g|g(t).
191AU4c Detectors: Ge(Li), Si(Li). Presented level scheme, no numerical
191AU5c E|g data are listed.

191AU c
191AU c 1985Va07: Source was produced from a 170 MeV {+16}O beam on a
191AU2c hafniumcarbide target, mass-separated and continuously implanted at
191AU3c 50 keV in a high purity Fe foil. The |g-decay was measured by three
191AU4c Ge detectors, one at 0|' and other two at 90|' to the field direction.
191AU5c Deduced |g-multipolarity, |d, magnetic moment of the isomeric state.

191AU3cN unplaced |g's in the level scheme. Total I|g of the unplaced |g's
191AU4cN is 37% of I(|g+ce) to (g.s. + 11 keV level).
