General Comments:

See 191Ir(n,γ) E=res dataset for the energies of a number of resonances with energies near 6198 keV; they have not been included here.

Specific activity of 192Ir: 265.2 11 kBq/g (2001Fo01).

Levels: Band structure is discussed in 1997BaZV, 1994Ga05 and 1991Ke10; assignments are based on Nilsson model calculations for plausible configurations, spectroscopic factors from transfer reactions and γ decay patterns.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β-), S(n), S(p), Q(α): from 2011AuZZ (cf. 1459.7 19, 6198.11 11, 5728.5 11, 1758.0 12, respectively, from 2003Au03).

E(level): From 191Ir(n,γ), except as noted, for levels for which decay γ’s have been observed. Weighted average of all available data, except as noted, for other levels.

Jπ(level): Justification for adopted values are given in comments. Additionally, with Jπ=1+,2+ for capture states (in s-wave capture from 3/2+), J=0,1,2,3 for levels fed by primary γ’s in 192Ir(n,γ) E=thermal.

T1/2(level): From γγ(t) or centroid shift in 191Ir(n,γ): secondary γ’s, except as noted.

I(γ): Relative photon branching from each level; values are from 192Ir(n,γ).

These data suggest a (0-,3-) level at 130.8 6. (n,γ) E=thermal populates a nearby Jπ|<2- 128.7 level and (n,γ) E=2, 24 keV would be expected to do likewise. Possibly the energy mismatch is not significant, but the existence of a 131+129 doublet cannot be ruled out. If there were a doublet, the (n,γ) E=2, 24 keV data would favor J=0 for the 129 level (since π=- is established independently for that level) and Jπ=1+,2+ for a 131 level.
