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. WebThe spins of the ground states of Cs 137 and Ba 137 are known to be 7/2 and 3/2, respectively. The shape of the 518-kev beta-ray spectrum has been measured and found to correspond to the correction factor G ′ = (W 0 − W) 2 + A (W 2 − 1) in agreement with previous work. This is the shape predicted by the Fermi theory of beta-ray decay and the …
