136BA c 1979Oh03,1977OhZO: {+136}Cs activity from the {+138}Ba(|g,pn)
136BA2c reaction followed by chemical separation. Measured E|g, I|g,
136BA3c |g|g(|q), |g(|q,H,t), and |b|g(t) using plastic scintillator, NaI(Tl)
136BA4c detector and two Ge(Li) detectors. Deduced T{-1/2} of 2140- and
136BA5c 2207-keV levels and g-factor of 2140-keV level.
136BA c 1975Gr31: {+136}Cs activity from two methods, 1) irradiation of
136BA2c {+235}U in reactor followed by chemical separation 2) from the
136BA3c {+138}Ba(d,|a) reaction followed by chemical separation. Measured
136BA4c E|g, I|g using Compton-suppression spectrometer and large volume
136BA5c Ge(Li) detectors and x-rays using Ge(Li) x-ray detector.
136BA c 1973Ba24: {+136}Cs activity from the {+138}Ba(d,|a) reaction with
136BA2c E(d)=25 MeV. Measured E|g, I|g, |g|g, |b|g(t), |g|g(t), |g|g(|q)
136BA3c using Ge(Li) and NaI(Tl) detectors and plastic scintillators.
136BA c 1967Fu05: {+136}Cs activity from U(p,f) reaction followed by chemical
136BA2c separation. Measured E|g, I|g using Ge(Li) detector, ce(K)'s using
136BA3c Si(Li) detector and |b|g(t).
136BA c 1965Re07:{+136}Cs activity from the {+138}Ba(d,|a) reaction with
136BA2c E(d)=20 MeV. Measured |b{+-}'s and ce's using double-focussing
136BA3c beta-ray spectrometer; E|g, I|g, |g|g-coincidences and |g-|S|g|g
136BA4c using NaI(Tl) detector; |b|g|g-coincidences using anthracene beta
136BA5c detector.

136BA cG $1977OhZO, 1975Gr31 and 1973Ba24 all provide detailed I|g
136BA2cG information. Particularly below 300 keV, there is considerable
136BA3cG differences among the different measurements. As 1975Gr31 and
136BA4cG 1973Ba24 are in closest agreement, and since 1977OhZO is a secondary
136BA5cG publication, the evaluator adopts an average of the 1975Gr31 and
136BA6cG 1973Ba24 values. Results from 1977OhZO are indicated in the comments.
136BA cG $I|g(K| x ray)=22% {I4} (1959Gi50; NaI)
136BA cL E$From a least-squares fit to E|g, by evaluator.

136BA2cG results of 1967Fu05 and 1965Re07, except as noted and for the 67|g
136BA3cG and 86|g where 1965Re07 apparently had source thickness and other
136BA4cG problems. 1965Re07 also measured ce(M)'s.
136BA cG M$From the Adopted Gammas. Support for multipolarities from this
136BA2cG dataset indicated in the comments. In general, multipolarities are
136BA3cG derived from |a(K)exp and K/L ratios, except where noted.
136BA cG MR$From the Adopted Gammas. For cases where |a(K)exp and K/L ratio
136BA2cG are known, value is derived by evaluator using BrIcc mixing code.
136BA cG E(Z)$E|g differ by 3 to 5 |s's from results of least-squares
