E(level): From a least-squares fit to Eγ for levels above 605+x keV. When ΔEγ is not explicitly given, it is assumed that ΔEγ=1 keV

Jπ(level): Based on deduced transition multipolarities using γ(θ) and α(K)exp (1981Th03), and angular correlation (1993Cl02)

M(γ): From γ(θ), α(K)exp, α(L)exp and intensity balances in 1981Th03, unless otherwise stated

It is unlikely that the isomer decays via 50.7-keV, M2 transition to the 2546.37+x-keV, 15- level, since B(M2)(W.u.) ≈ 14 W.u., which would exceed RUL by more than 3σ. It is suggested in 1981Th03 that the depopulating transition is most likely E1 or E2, thus requiring an intermediate level with Jπ=15+, 16- or 17- which has not been observed yet.
