Disintegration ofTe119

Abstract

1348 GORDON, LARSH, SIKKELAND, AND SEABORG result, it is inferred that fission results only from reactions in which a compound nucleus is formed from the carbon particle and the gold nucleus. This observation is in contrast to those in the uranium-plus-carbon system, in which, at higher bombarding energies (^90 Mev), there is incomplete momentum transfer in some of the reactions that lead to fission. 23 The slight increase in fragment kinetic-energy release with increasing bombarding energy is attributed to an increase in the average number of neutrons evaporated prior to fission. Thus, the fissioning nuclei

Decay Schemes of theTe119Isomers

“…The decay of these isomers has been the subject of several previous works, [10][11][12][13][14] the most definite being the Nal(Tl)-scintillation spectroscopic study by Kan tele and Fink 13 and the conversion electron work by Svedberg and Andersson. 14 The Ge(Li) work by Berzins 15 In this work, with additional measurements of internal conversion coefficients and directional correlations between coincident 7 rays, we were able to make more definite spin and parity assignments.…”
