191IR c 1969Ma07: {+190}Os(n,|g); Ge(Li); double focusing magnetic spec;
191IR2c ce-ce delayed coin.
191IR c 2005Ni12: {+190}Os(n,|g); accurately calibrated HPGe (2002Ha61).
191IR c I(L{-|b} x ray)=0.394 {I35}, I(L{-|a} x ray)=0.281 {I34}, I(L{-|g} x
191IR2c ray)=0.091 {I11}, I(L{-1} x ray)=0.011 {I10}, Ge(Li) (1989BeYR).

191IR cN NR I|g per 100 parent decay, assuming |b feeding only to
191IR2cN the 11/2- state.
191IR cG RI I|g per 100 parent decay deduced by evaluator assuming |b
191IR2cG feeding only to the 11/2- state and considering I|g(47)(1+|a)=
191IR3cG I|g(82.4)(1+|a). These data are more consistent with the
191IR4cG data presented in 1986BrZQ and 1978LeZA. The data presented in
191IR5cG 1995Br38, from selected Ice of 1969Ma07 and |a, assuming no |b{+-}
191IR6cG feeding to g.s., was slightly higher. The data are in radioactive
191IR7cG equilibrium with {+191}Ir(4.9 s). Comparison of Ice for E(ce) differing
191IR8cG more than 20 keV have an additional 20% of relative uncertainty due
191IR9cG to differences in absorption (1969Ma07). Precise I|g values
191IRacG result from decay scheme characteristics.
