E(level): For the states connecting γ’s, E(levels) are from level scheme and adopted γ radiations using least-squares fit to data.
Jπ(level): From γ(θ) of 192Pt(10B,5nγ) and systematics for the heavier odd-mass Bi isotopes (1986Ch01), the assignments of states to the bands with the fitting spin of 15/2 using the I(I+1) relationship of 187Re(16O,5nγ) except as noted.
T1/2(level): From γγ(t) or γ(t) measurements in 192Pt(10B,5nγ), except as noted.
I(γ): Relative photon branching from each level
