E(level): From least-squares fit to Eγ, assigning 1 keV uncertainty to Eγ data for which the authors did not state an uncertainty, except for levels observed only in (t,p) reaction.

Jπ(level): Based on the systematics for band structures of the even Dy isotopes, unless otherwise noted.

E(γ): From 165Dy(n,γ), E=thermal, except as noted.

I(γ): Relative photon intensity normalized to 100 for strongest γ deexciting each level; from 165Dy(n,γ) E=thermal, except as noted. Branching from β- decay is in good agreement with that from (n,γ).

M(γ): From subshell ratios and/or α(K)exp in (n,γ) E=thermal.
