E(level): From least-squares fit to γ-ray energies for levels connected by γ transitions assuming ΔEγ=1 keV if not given; for other excited levels with proton decay, energies are from measured proton energies in ⁴⁸Fe ε decay

J^π(level): Assignments based on allowed β feedings in ⁴⁸Fe ε decay, unless otherwise noted.

E(γ): From ⁴⁸Fe ε decay, unless otherwise noted
