E(level): From least-squares adjustment of Eγ. Energies assume excitations of x and y, respectively, for the lowest energy level observed in (HI,xnγ) studies (Jπ=(9/2-)) and for the bandhead of the possible h11/2 coupled structure. From level energy systematics for odd-A Au isotopes, x=90 50 and y=260 20 for the lowest 9/2 and 11/2 levels, respectively, appear to be reasonable estimates. α 5/2- level also is expected very close to the g.s.

Jπ(level): From (35Cl,4nγ), based on measured DCO ratios and deduced band structure, assuming Jπ=9/2- for the lowest-energy level observed in that study (consistent with systematics for Au isotopes), except as noted.

M(γ): From measured DCO ratios in (35Cl,4nγ).
