E(level): From least-squares fit to adopted Eγ, except as noted. The evaluator has assumed an uncertainty of 0.6 keV in Eγ data for which the authors did not state an uncertainty; this represents the largest difference between the data from the three different sources for which specific uncertainties are not known.

J^π(level): Values given without comment are from ¹⁷⁶Yb(²⁸Si,Xγ), ¹⁷⁶Yb(³¹P,Xγ); they are tentative values from 2005Pa48 based on previously-known Jπ for some low-spin states, comparison with theoretical calculations and the assumption that yrast J values increase with excitation energy. Assignments are supported by comparison of corresponding states in neighboring Zr isotopes using a weak-coupling scheme.
