Abstract

Using

K^{0}' s

produced by the charge exchange of

K^{+}

, we have measured the proper-time dependence of the decays

K^{0} \to π^{0} π^{0}

. Analysis indicates that a third-quadrant solution for the phase of

η_{00}

is unfavored by more than 2 standard deviations. A first-quadrant solution is acceptable.
