Interference Effects in NeutralK-Particle Decay

Abstract

An analysis is made of interference effects between the ${K_1}^0$ and ${K_2}^0$ components of a neutral $K$ beam for decay in the channel ${\pi }^{+}+{\pi }^{-}+{\pi }^0$. The effects discussed, though expected to be small, may just be detectable. If so, they would serve as a test of the proposed $\left|\Delta T\right|=\frac{1}{2}$ rule.
