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. The isomer
139SM5c half-life measured over a period of |?200 s; two groups, one with
139SM6c T{-1/2} of 17.9 s {I6} and one with a feeding T{-1/2} of 17.9 s {I6}
139SM7c and |a decay T{-1/2} of 10.7 s {I6}.
139SM c 1986Re11: {+139}Eu produced in {+112}Sn({+32}S,3p2n),E=170 MeV and
139SM2c {+106}Cd({+35}Cl,2p),E=191 MeV reactions. Identification by means of
139SM3c |g rays observed in {+139}Sm IT decay. Measured half-life; He jet.
139SM c 1975Va14: measured |b spectra, |b|g-coin, |g spectra, ce; deduced
139SM2c shape implications for unhindered 11/2- to 11/2- |b transition
139SM c All data are from 1986De35, except as noted.
139SM cE $The |b feedings and log| {Ift} values are considered as apparent as
139SM2cE the decay scheme seems poorly known
139SM cG M,MR$From Adopted Gammas
139SM cG E(B)$From {+139}Sm IT decay.
139SM cG E(A)$Observed clearly only in the coincidence spectrum.
139SM cG RI(D)$From adopted branching ratios, |a, and |SI(|g+ce) feeding
139SM2cG level. Strong direct feeding of (11/2)- level indicates levels below
139SM3cG 457 are not directly fed (evaluators).
139SM cG RI(E)$From I(|g+ce) and |a.
139SM cG E(F)$From Adopted Gammas
139SM cG RI(H)$From I|g(1+|a)(189|g) and adopted branching ratios and |a's.
139SM cG RI(X)$Value is not given due to their time-dependency arising from
139SM2cG comparable half-lives of the {+139}Eu parent (17.9 s) and 10.7-s
139SM3cG isomer at 457 keV in {+139}Sm populated in this decay. Apparent
139SM4cG values from intensity balances are given under comments.
139SM cG CC$Theoretical values from BrIcc code. When |d(E2/M1) is not given,
139SM2cG listed value overlaps those for pure M1 and for pure E2
139SM cL E$|DE|g=0.5 keV assumed in least-squares analysis when not given.
