I/sup 136/, produced from the slow neutron fission of uranium, has been studied with scintillation techiques. From the single-crystal (NaI)and gamma- gamma coincidence spectra, gamma rays were found at energies of Also, from single- crystal (anthracene) and beta-gamma coincidence measurements, four beta-ray ground were observed with energies of 2.73, 4.23, 5.62, and 7.00 Mev, where the latter represents the I/sup 136/-Xe/sup 136/ mass difference and is present in about 6% of the total beta-ray transitions. A partial decay scheme has been proposed, with energy levels in Xe/sup36/ at 1.32, 2.64, 2.84, 3.03, 3.23, measured as 82.8 plus or minus 1.5 seconds. In the course of this investigation a source of 3.8-minute Xe/sup137/ was prepared, and was found to emit prominent gamma rays of 0.26 and 0.45 Mev. (auth)
