E(level): From a least-squares fit to Eγ

Jπ(level): From deduced γ-ray transition multipolarities using α(K)exp and/or K/L in 204At ε decay and α(K)exp and/or γ(θ) in 204Pb(α,4nγ), 198Pt(12C,6nγ), unless otherwise specified

M(γ): From α(K)exp and/or K/L in 204At ε decay, unless otherwise specified. For transitions depopulating the 3083.6-keV level and levels above it, the data are from α(K)exp and/or γ(θ) in 204Pb(α,4nγ), 198Pt(12C,6nγ)
