ON THE SYSTEMATICS OF TRANSITION PROBABILITES OF M4 TRANSITIONS OF THE TYPE h$sub 11$$.$$sub 2$ $Yields$ d$sub 3$ OVER $sub 2$. DECAY OF Te$sup 133$m
A careful analysis is made of the radial matrix elements of M4 transitions of the type h/sub 11/2/ yields d/sub 3/2/. It has previously been claimed that the matrix elements systematically increase towards the magic numbers. Especially the matrix element of Te/sup 133m/ was found to be large in comparison with the matrix elements of the other Te isomers. For this reason the decay of Te/sup 133m/ has been studied. The half-life of the isomeric state was found to be 53 plus or minus 4 m with a decay energy of 334.0 plus or minus 0.3 kev. Further, a large beta -branching of 87% from the isomeric level was found. This reduces the empirical matrix element of Te/sup 133m/ to the order of magnitude of the other matrix elements in the isomers of tellurium. It must therefore be concluded that there are no certain experimental proofs that the matrix elements of M4 transitions are larger when shells are almost filled. (auth)
