General Comments:

1962Ha16: 129Sn produced and identified in 170-MeV proton irradiation of uranium target followed by chemical separation; measured half-life. Two activities were reported in this work with half-lives of 1.0 h and 8.8 min, the former has not been confirmed, the latter corresponds to 6.9-min isomer. α 1.8H activity reported by 1960Al03 and assigned to 129Sn decay has never been confirmed

1962Dr01: 129Sn produced and identified in thermal neutron fission fission of 235U followed by chemical separation, measured half-life and gamma spectra. Only a 6.2-min activity identified. No longer-lived activity was found as reported in 1962Ha16

Later decay studies: 1967Bi15, 1972Iz01, 1974Fo06, 1974Gr29, 1980De35, 1982Hu09

Precise mass measurement by Penning-trap system: 2005Si34

Levels: No levels are known from 130In β-n decays

Q-value: S(2n)=13279 22, S(2p)=26695 23 (2012Wa38)
