E(level): From least-squares fit to Eγ data with reduced χ2=0.97. For levels not populated in γ-ray studies, the values are generally from (3He,α)
Jπ(level): In many cases arguments from particle-transfer reactions are used, target Jπ=0+ for (p,d), (d,t), (3He,α), (p,pn), (p,π-) and (n,α) reactions; 1/2- for (3He,t); 5/2+ for (p,t); and 9/2+ for (3He,n) reactions
T1/2(level): From ΔS(a) in (α,nγ) (1974Bi13) for low-spin levels, from RDDS for high-spin levels (1986Wa25), unless otherwise stated
