E(level): For the states connected with Eγ, E(level) are from Eγ using least-squares fit to data.
Jπ(level): Based on γ(θ), T1/2, ce, and systematic properties of the odd-A Bi isotopes; assignments are tentative because presumed 9/2- ground state (π h9/2) is not firmly established. Assignments are from 181Ta(20Ne,6nγ), except as noted. Jπ for SD band members from band membership. SD band assignment from configuration with neighboring nuclei.
T1/2(level): From γ(t) pulsed-beam timing measurements in (HI,xnγ), except as noted.
E(γ): From 181Ta(20Ne,6nγ)
I(γ): Relative photon branching renormalized to 100 for the strongest branching from each level. For SD band, values are relative transition intensities within the band
M(γ): From DCO value in 181Ta(20Ne,6nγ)
