E(level): From least-squares fit to adopted Eγ, except as noted. The normalized χ2=2.0 cf. χ2 (critical)=1.4, and 4 Eγ values are 3σ or 4σ from fitted value. Note that additional levels exist in the vicinity of 2200 keV and 3200-3800 keV as evidenced by the β- strength distribution deduced from absorption γ spectrometry (see 93Sr β- decay); these are not included here because specific level energies have not been determined.

M(γ): From α(K)exp in 93Sr β- decay, except as noted.

T1/2(93Sr) from 1972Eh02 also differs significantly from adopted value. Datum from 1966No08 results from least-squares fits to four-component decay curve for Y fraction, but authors do not themselves assume this value in later calculations.
