E(level): From a least squares fit to the adopted γ-ray energies.
Jπ(level): The assignments are based on rotational band structure; comparison of experimental spectroscopic factors with theory in (3He,d) and (α,t); and the relative cross sections in (d,d’) studies. Additional arguments in the comment section.
