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
