E(level): From a least-squares fit to Eγ, by evaluator.
Jπ(level): For levels with spin assignments above 1.5 MeV, there is the assumption of increasing spin with increasing excitation energy for levels populated in heavy-ion induced reactions. Based on systematics of neighboring n=50 nuclei, negative parity is proposed for the 1543-, 1866-, 3094-, and 3457-keV levels in both 208Pb(18O,Xγ) and 238U(82Se,83Asγ) (2011Po13,2012Sa46).
M(γ): From γ(θ) and RDCO in 238U(82Se,83Asγ).
