General Comments:

Energies and structures of various states were calculated in 1971Ga20. See also 1976Ch22 and 1972Be91 for calculated energies.

Quadrupole and hexadecapole deformations were calculated from single-particle energies in 1976Ch22.

Q-value: Note: Current evaluation has used the following Q record

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.
