E(level): The excited levels are from 230Ra β-. Since the decay scheme is not well established, the excited levels and the placements of gammas should be considered tentative. See 230Ra β- decay for spins and parities proposed in 1980Gi04.
Jπ(level): Adopted from 230Ra β- decay based on logft values.
E(γ): From 230Ra β- decay (1980Gi04).
I(γ): Relative photon intensity deexciting each level (1980Gi04).
