Abstract

The rate of the

CP

-nonconserving decay

K_{L}^{0} \to 2 π^{0}

has been measured relative to that of

K_{L}^{0} \to 3 π^{0}

using a monoenergetic

K

beam and a nearly

4 π

solid-angle detector system employing lead-plate spark chambers and shower counters. The measured branching ratio 1.31% ± 0.18% (statistical) ±25% (systematic) leads to a value for the

CP

-nonconservation parameter

{| η_{00} |}^{2}

of (14.1 ±3.4) ×

10^{- 6}
