The disintegration of I/sup 124/ (4.2 days) was studied with the help of magnetic spectrometers and scintillation spectrometers. The dfsintegration occurs 71% by electron capture and 29% by positron emission. Three positron groups were found having end-point energies of 2l30 (46.0%), 1531 (46.4%, and 786 (7.5%) kev. The most energetic positron group has a shape characteristic of DELTA I = the J-57 engin 2, yes. Positron-gamma coincidence experiments show that this group Boss to the ground stute. Gamma rays of energies 2700, 2500, 2100, 1700, 1520, diation and Te K x-rays were fouad and the relative intensities measured. A disintegration scheme, consistent with the levels of Te/sup 124/ as detemined from the decay of Sb/sup 124/ was established. No beta rays were found, showing that a transition to Xe/sup 124/ is highly improbable. The former work on I/sup 123/ (13.5 hours) was substantiated and, in addition, it seems highly unlikely that any positrons are emitted from I/sup 123/. (auth)
