194IR c {+194}Ir isomer was produced via {+193}Ir(n,|g) E=thermal in all
194IR2c studies below.
194IR c 1968He11: thermal neutrons were from the Rossendorfer research reactor.
194IR2c Measured E|g, I|g, with a Ge(Li) spectrometer.
194IR c 1968Lu01: thermal neutrons were from the Triga MK II reactor. Measured
194IR3c E|g, I|g, |g(t) with a Ge(Li) detector.
194IR c 1971Kr09: thermal neutrons were from the Munich research reactor (FRM).
194IR2c Measured E|g, I|g with a Ge(Li)-NaI(Tl) pair spectrometer.
194IR c 1988Ba49: thermal neutrons were from the reactor at Wurelingen.
194IR2c Measured E|g, I|g, |g|g-coin, |g(t), with a crystal spectrometer and a
194IR3c Ge(Li) spectrometer; measured E(ce), I(ce) with a |b spectrograph at
194IR4c the Physics Institute, Latvian Academy of Sciences. Deduced levels, J,
194IR5c |p. See also 1993BaZP, 1993Ko59
194IR d 1993KoZT, 1994KoZQ superceded by 1993Ko59
194IR c 1998Ba85 (also 1998Ba42): thermal neutrons were from the Gatchina VVRM
194IR2c reactor. Measured E|g, I|g, E(x ray), I(x ray), |g|g-coin with a HPGe
194IR3c detector and a NaI(Tl) scintillator.

194IR c The 31.85-ms isomer was proposed at E=195 keV based on a 83|g-112|g
194IR2c cascade by 1968Lu01, 1968He11 and 1971Kr09; later, it was proposed at
194IR3c E=147 keV by 1988Ba49 and confirmed based on |g|g coin measurements
194IR4c in 1993BaZP, 1993Ko59, 1994KoZQ
194IR cG $Measured relative K| x ray intensity of 677 {I26} (weighted
194IR2cG average of 770 {I70} (1968He11) and 670 {I20} (1968Lu01)) compares
194IR3cG with 625 {I30}, deduced by evaluators from decay scheme.
194IR cG E$From {+193}Ir(n,|g) E=th. All value are from 1998Ba85; only 84|g
194IR2cG (82.34|g+84.29|g doublet) and 112|g are seen in 1968He11 and 1968Lu01.
194IR cG E(X)$From ce spectrum and not reported in |g-ray data in (n,|g) E=th
194IR cG RI(A)$Deduced by evaluators from I(|g+ce) intensity balance at the 82
194IR2cG level with deduced I|g=2.0 {I2} of 29.9|g (the only |g that feeds the
194IR3cG 82 level), relative I|g values of 39.2|g and 82.3|g from (n,|g) E=th,
194IR4cG and theoretical conversion coefficients from BrICC.
194IR cG RI(B)$Deduced by evaluators from relative I|g values of 27.9|g, 29.9|g
194IR2cG and 112.2|g from the 112 level in (n,|g) E=th, and I|g(112.2|g)=100
