General Comments:

Levels: For the interacting boson-fermion model, see 1989Wo04

Levels: For the theoretical investigation of hyperfine interactions and isotope shifts in gold, see 1984Ah07.

Levels: 1978Vi01 proposed rotational bands built on g.s. and 1/2+ first-excited state using Nilsson-particle asymmetric-rotor model. See 1978Mu08 for Nilsson-model interpretation of π=- states

Levels: For comparison with level spectra in 191Au, 193Au, 195Au, see 1974Tj02

Levels: For FCC (face-centered cubic) nuclear model, see 1987Da18 and 1987Co21.

E(level): For the states connecting γ rays, E(levels) are from adopted scheme and adopted γ radiations using least-squares fit to data.

E(γ): From 197Au(n,n’γ), except where noted otherwise

I(γ): Relative photon branching from each level. Data are from (n,n’γ), except as noted.
