194IR c 1978In01: {+194}Os source was prepared by drop evaporation onto a thin
194IR2c mylar film. |g rays were detected with a large volume Ge(Li) detector
194IR3c and x rays were detected with a Si(Li) detector (FWHM=240 eV at 6.4
194IR4c keV). Measured E|g, I|g, E(x ray), I(x ray). Deduced levels, J, |p,
194IR5c conversion coefficients, multipolarity, |b-decay branching ratios, log

194IR c 1965Jo10: {+194}Os source was prepared by irradiation of a metallic
194IR2c Os in Oak Ridge LITR. |g and x rays were detected with a NaI
194IR3c spectrometer and electrons were detected with a anthracene detector.
194IR4c Measured E|g, I|g, E(x ray), I(x ray). Deduced levels, J, |p,
194IR5c conversion coefficients, multipolarity, |b-decay branching ratios, log
194IR6c {Ift}.
194IR c 1964Wi07: {+194}Os source was prepared by irradiation of a natural Os
194IR2c metal with a thermal neutron flux from MTR. |g rays were detected with
194IR3c NaI(Tl) detectors. Conversion electrons were detected using a gas-flow
194IR4c proportional spectrometer. Measured E|g, I|g, E(ce), I(ce), E|b, I|b.
194IR5c Deduced levels, J, |p, conversion coefficients, multipolarity, |b-decay
194IR6c branching ratios, log| {Ift}. See also 1966Wi06
194IR c 1972KiZY: measured E|g, I|g, x rays.

194IR4cN I(|g+ce)(43|g)/I|b=0.27 {I5}. This ratio gives I|g normalization=0.019
194IR5cN {I4}, which disagrees with that deduced from the |g-ray data

194IR cG RI$from 1978In01. 1964Wi07 give I|g=0.183 {I11} and

194IR3cG 1978In01 that is also consistent with the non-observation of 82.3|g.
194IR4cG It should be noted that 1978In01 incorrectly quote this limit as 0.002
194IR5cG in two places in the paper while it is correctly given as 0.2 in two
194IR6cG other places. An examination of the spectrum shown by the authors
194IR7cG clearly reveals the discrepant values
