242PU2cG (1956Al41), 44.55 (1960As05). The uncertainty in the value of
242PU3cG 1955Ba31 comes from 1956Ho54
242PU cG RI$photons per 100 {+242}Am |e decays from 1980VyZZ.
242PU2cG Other: 0.014 from work of 1955Ba31. These authors measured the
242PU3cG total conversion electrons of the 44.5|g relative to the |b
242PU4cG intensity from {+242}Am |b{+-} decay to be 154/1200, with no
242PU5cG quoted uncertainty. This ratio, along with %|b{+-}=83.0 gives
242PU6cG Ice(44.5|g)=10.7 per 100 {+242}Am decays and thus I|g=0.014, in
242PU7cG excellent agreement with the value from 1980VyZZ.
242PU8cG The authors of 1955Ho67 measured I[ce(L1)+ce(L2) 44.545|g from
242PU9cG Am |e decay]:I(ce 42.13|g) from Am |b{+-} decay)=360:1380
