E(level): From a least-squares fit to Eγ data for levels connected with γ transitions, and from transfer reactions for other levels, unless otherwise noted.

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 line shapes 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 given for photon branchings for multiply-placed transitions
