Abstract

It is shown that the observation of interference between

K_{L}

and

K_{S}

decays in the partial decay rate into any nonleptonic mode is direct evidence of

CP

violation. The examples of

K^{0} \to γ + γ

and

K^{0} \to π^{+} + π^{-} + γ

are analyzed in detail; a large interference effect may be possible in either of these cases if there is a large

CP

violation associated with interactions involving photon emission.
