E(level): From least-squares fit to Eγ, except as noted.

Jπ(level): Values given without comment are from (90Zr,pγ) and based on deduced band structure, transition multipolarities, i13/2 band alignment and analogy to very similar structures in neighboring odd-A Au isotopes.

M(γ): Based on γ anisotropy data in 90Zr(90Zr,pγ), except as noted, assigning Δπ=(no) for intraband transitions.
