E(level): From least-squares fit to Eγ values for levels populated in γ-ray studies, assuming ΔEγ=0.5 keV, when not stated. For levels not observed in γ-ray studies, values are from weighted averages of available data with uncertainties.
Jπ(level): For low-spin (J|<6) states, supporting arguments are given for individual levels. For high-spin (J>6) levels, the assignments are based on γ(θ) data in (7Li,p2nγ), unless otherwise stated. In assigning Jπ values the evaluators assume that spins tend to increase with excitation energy.
