Angular Asymmetry Theorems for Decay Products

Phys. Rev. 123, 637 – Published 15 July 1961
Murray Peshkin


The method of Eberhard and Good, for using decay angular distributions to determine the spins of unstable systems, is developed. Their inequality, which expresses the impossibility of getting too symmetric a decay pattern from an asymmetric initial state, is tightened. The results are generalized to include spinning decay products. The Adair analysis is generalized in the same framework.
