E(level): Deduced by evaluators from least-squares fit to adopted γ-ray energies, unless otherwise specified.

Jπ(level): Spin, parity, and Nilsson-state asignments are based on comparison of experimental (t,α) cross-sections with calculated values (1977Th04), and on measured angular momentum transfer values (L) in (p,α) reactions. The assigned spins/parities are consistent with the γ-ray decay pattern observed in 229Ra β- decay.

E(γ): From 229Ra β- decay.
