Abstract

Using

K^{0}

produced by

K^{+}

charge exchange in Be, we have measured the charged-to-neutral branching ratio of

K_{1}^{0}

. We obtain 2.285 ± 0.055 to be compared with the

| Δ I | = \frac{1}{2}

rule prediction of 2.00. This 5-standard-deviation violation gives

Re (\frac{A_{2}}{A_{0}}) cos (δ_{2} - δ_{0}) = 0.0345 \pm 0.007

.
