E(level): From least-squares fits to γ-ray energies

Jπ(level): Tentative assignments based primarily on systematics in lighter n=83 above 147Gd (and n=82) isotones, assigned configurations, and measured multipolarities, including g.s. and the highest lying 15 μs isomeric state (see IT decay dataset, 1993Mc03)

Jπ(level): See 1993Mc03 for detailed discussion of configurations.

T1/2(level): Measured in the IT decay dataset unless otherwise noted

M(γ): From intensity balance deduced from total internal conversion coefficients in IT decay.
