E(level): From least-squares fit to Eγ, except where noted. ΔE=1 keV was assumed for missing Eγ uncertainties. Levels not connected by Eγ are from particle dataset.

J^π(level): From population by E1 (or probable E1) γ from 1/2⁺ in ¹⁶⁸Er(n,γ) E=resonance, except as noted.

E(γ): From ¹⁶⁸Er(n,γ) E=thermal, except where otherwise noted.

I(γ): Relative photon branching from each level; values are from ¹⁶⁸Er(n,γ) E=thermal, except as noted. Upper limits are given for photon branching ratios affected by multiple placement.
