General Comments:

129I identified by 1949Pa19, 1949Li09 and 1951Ka16; also an earlier preliminary report by S. Katcoff in Phys. Rev. 71, 826 (1947). Later studies of 129I decay: 1985Ba73, 1977Ra23, 1965Wa13, 1954De17

Q-value: S(2n)=15666 5, S(2p)=16386 6 (2012Wa38)

E(level): From least-squares fit to the adopted Eγ values for levels populated in γ-ray studies. For others weighted averages are taken

Jπ(level): For levels populated in high-spin studies, ascending order of spins with excitation energy is assumed based on yrast pattern of population
