139SM c 1986De35: {+139}Eu produced in {+144}Sm(p,6n),E=50-90 MeV.
139SM2c Identification by means of T{-1/2}|?22 s, production threshold
139SM3c energy, and constancy of I|g as a function of bombarding energies.
139SM4c Measured E|g, I|g and x rays, |g|g, isomer half-life, ce.
139SM5c The isomer half-life measured over a period of |?200 s; two groups, one
139SM6c with T{-1/2} of 17.9 s {I6} and one with a feeding T{-1/2} of 17.9 s
139SM7c {I6} and |a decay T{-1/2} of 10.7 s {I6}.
139SM c 1975Va14 (also 1973VaYZ, 1971Va22): measured |g and ce spectra
139SM c All data are from 1986De35, except as noted. Decay scheme based on
139SM2c |g-ray singles, |g|g-coin, energy sums, and conversion
139SM3c electron coefficients and differs from that of 1973VaYZ and 1975Va14
139SM4c in the order of the 112|g and completeness.
139SM cG $|a(K)exp: from concurrent measurement of ce(K) and |g.
139SM cG $K/L are from 1973VaYZ, except for K/L(190.1|g).
139SM cG M,MR$From Adopted Gammas, based mostly on data in the present decay
139SM cG E(A)$Seen only in coincidence spectra.
