E(level): From 252Cf SF decay (2017Hu09)

Jπ(level): Based on γ-ray multipolarities from γγ(θ), linear pol, and /or band assignments in 248Cm SF decay and 252Cf SF decay datasets as well as the fact that J values generally increase with excitation energy for heavy-ions induced reactions

E(γ): From 252Cf SF decay dataset. None of the measurements done in 252Cf SF decay (2017Hu09) or 248Cm SF decay (2000Ur04 and 1996Be06) report uncertainities for Eγ values which however are consistent with one another (the energies of a same γ-ray fluctuate typically by less than 0.5 keV). The largest and most recent set of Eγ values was adopted here unless otherwise noted

I(γ): From 252Cf SF decay dataset (2017Hu09).
