E(level): From a combined fit of levels and gammas, except where noted or where cross references clearly indicate other source.
Jπ(level): Values given without comment are from 167Er(209Bi,209Bi’γ), based on observed band structure.
T1/2(level): From Doppler-broadened γ-ray lineshapes in Coulomb excitation (1985Oh03), except where noted.
E(γ): From 166Er(n,γ) E=thermal, except where noted.
I(γ): Relative photon branching from each level; from (n,n’γ), except where noted. Upper limits are reported for photon branchings affected by multiple placement.
