139LA c 2012Da17: measured E|g, I|g, |g|g coin, T{-1/2} of {+139}Ba
139LA c 2012Da04: measured E|g, I|g, T{-1/2} of {+139}Ba
139LA c 2001Za08: {+139}Ba from {+138}Ba(n,|g), measured E|g, I|g, |g|g using
139LA2c combination of HPGe, Ge(Li), BGO-Compton suppressed Ge detector, and
139LA3c NaI(Tl) detector
139LA c 1986Fa08: measured E|g, I|g. The authors essentially confirmed results
139LA2c of 1969Be15, with a few additional weak |g rays
139LA c 1980Ge04: measured E|g, I|g and half-life of {+139}Ba decay and
139LA2c |b|g-coincidences (4|p,NaI).
139LA c 1978La03: measured E|g, I|g between 1.2 and 2.0 MeV and investigated
139LA2c ambiguities in I|g between 1968Hi13 and 1969Be15.
139LA c 1975Fl07, 1969Su01: measured |b|g-coin
139LA c 1969Be15, 1968Hi13: measured E|g, I|g, |g|g coin
139LA c 1969Su01: measured E|g, I|g, |g(t) (NaI) and |b|g-coincidences and
139LA2c |b|g(|q) (scin,NaI).
139LA c 1524 keV level from 1980Ge04 was established as belonging to {+42}K
139LA2c in 2012Da17
139LA cG $A 1042.9 with I|g=0.01 in 1988Fa06 was not confirmed by 2012Da04,
139LA2cG 2012Da17 and 2001Za08. Based on |g|g-coin and half-life analysis,
139LA3cG 2012Da17 assigned this |g to the decay of {+82}Br. In 2001Za08,
139LA4cG I|g<0.0005, consistent with non-observation
