WebBeta Decay of Cs137 The figure shows that two different decays are possible. 92% of the electrons from Cs137 are associated with a transition having an E max of 514 keV and 8% with an E max of 1176 keV. Some of the 662 keV Gammas are internally converted. Cs 137 (Lifetime 30 years) Z=55 b-, 514 keV (92%) b-, 1176 keV (8%) Ba137 (Metastable ...
WebFig. 3: decay scheme for Cs-137 As shown in fig. 3 94,7% of beta-minus decays ends in the exited state h 11/2-, and 5,3% goes to the ground state d 3/2+ of the Ba-137 nucleus. And a very small fraction in the 1⁄2+ – state. But not all of the 94,7% beta-decays ending in the h 11/2 - state decays to the ground state by gamma emission. greenhouse gas emission calculationsWebThe study of beta-decay spectra led to discovery of the neutrino.
