E(level): From (60Ni,2pnγ), except as noted; this assumes that the 13/2+ state is not the g.s.; the first 13/2+ state lies at E=186 in 171Os and at E=146 to ≈200 in 173Os.

Jπ(level): From (60Ni,2pnγ; based on likely quasiparticle configurations and comparison with similar structures in neighboring odd-A nuclei, except as noted.

E(γ): From (60Ni,2pnγ).
