General Comments:

Other Reactions:

93Zr(μ-,nγ) (1971Ba10): observed 267 level to g.s. transition (Eγ=265.7 6).

Levels: See 92Zr(n,γ) E=res dataset for neutron resonance energies and widths.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β-), S(n), S(p), Q(α): from 2009AuZZ (cf. 91.2 16, 6734.5 4, 9593 9, -3332.8 25, respectively, from 2003Au03).

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.

Jπ(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.
