E(level): From a least-squares fit to Eγ data, normalized χ2=0.65. Where uncertainty is not known it is assumed to be 1 keV
Jπ(level): From α(exp), γ(θ)(DCO) data, shell model calculations and systematics for n=80 even-even nuclei
M(γ): From α(exp), γ(θ)(DCO) data

Produced and identified by 1981AlZO and 1981Al23; tungsten target bombarded with 1 GeV protons.
The level scheme of 146Dy is constructed on the basis of ε decay data, γγ coincidences, γ(t), delayed proton measurements and the reactions data
