E(level): Level energies with ΔE|<1 keV are from least-squares fit to Eγ from ⁹²Sr β^- decay; others are from (d,α).

0.0	2-	3.54 h 1 % β^- = 100	Q=0.00 2 (2007Ch07), μ=-0.67 2 (2007Ch07) Δ<r²>(⁹²Y,⁸⁹Y)=+0.385 fm² (2007Ch07). E(level): Δ<r²>(⁹²Y,⁸⁹Y)=+0.385 fm² (2007Ch07).
430.51	(2)-		E(level): From ²³⁸U(⁸²Se,Xγ). The order of the 430γ-953γ cascade is uncertain in ⁹²Sr β^- decay, allowing either a 430 level or a 953 level; the former is adopted because the (d,α) reaction indicates a level at 440 30 but no level near 953 keV.
