E(level): From a least-squares fit γ-ray energies for levels (up to 3952) connected with γ transitions with ΔEγ; for levels (above 3952) only populated in transfer reactions, values are from (p,d), unless otherwise noted.
T1/2(level): From DSAM in (α,nγ), unless otherwise noted. Values are also available in (3He,αγ) using DSAM.
