MEASUREMENTS ON ELECTROMAGNETICALLY SEPARATED RADIOACTIVE ISOTOPES OF IODINE

Journal Article · · J. Inorg. and Nuclear Chem.
The mass range 124 to 135 of iodine isotopes formed in 170-Mev proton- induced fission of uranium has been studied using an electromagnetic isotope separator to prepare mass-detcrmined samples for Geiger-Muller counting. Relative formation cross sections are given for the shielded nuclides: 12.6 hr I/ sup 130/ (1.0), 25 min I/sup 128/ (0.7), 13 dav I/sup 126/ (0.4) and 4 day I/sup 124/ (O.1). The presence of a (2.6 plus or minus 0.8) hr half life in the mass 126 decay curve may indicate isomerism in I/sup 126/. Neutron deficient iodine isotopes down to mass number 118 were separated from spallation products of cesium. The following mass assignments are reported: I/sup 119/ (19 min) I/sup 120/ (1.4 hr), and I/sup 121/ (2.0 hr). (auth)
