E(level): From least-squares fit to Eγ.

Jπ(level): From Sn(60Ni,xnγ), except as noted. Values for the g.s. band follow from the assumption of a stretched Q γ cascade. Those for the π=(-) band are based on the observation that the lowest excited bands in light neighboring Os and Pt isotopes have π=- and odd J, and this band connects to the g.s. band at its 2+ state.

E(γ): From Sn(60Ni,xnγ), except as noted. Note, however, that although these data are in satisfactory agreement with those from 92Mo(84Sr,2p2nγ), they are usually higher than data from 116Sn(58Ni,2nγ). Major discrepancies are noted.

I(γ): From Sn(60Ni,xnγ).

M(γ): From asymmetry ratio in S(n)(60Ni,xnγ), assigning Δπ=(no) to intraband transitions.
