E(level): For levels connected with γ rays, values are from a least-square fit to γ-ray energies with ΔEγ or without ΔEγ (for which 0.5 keV is assumed) where measured Eγ is available, or taken from (α,γ) E=res where measured Eγ value is not available but E(level) has been deduced by authors from precise Eγ data which however are not listed in the references; for other levels with no γ, E(level) values are from various reactions as indicated, unless otherwise noted.
Jπ(level): When assigning Jπ to a level based on γ transitions from this level to a level of known Jπ, evaluators use the following rules: if Eγ<4 MeV, transitions are only considered to be E1,M1 or E2; if Eγ>4 MeV, M2 and E3 are considered to be possible. For α resonances populated in (α,γ) and (α,α) reactions, π=natural
T1/2(level): From (α,γ) E=res using DSAM, unless otherwise noted
