 A detailed description of the analysis of the decay of neutral kaons to $\pi^+ \pi^-$ in the CPLEAR experiment
 CPLEAR Collaboration(s)
 (2000)
 A detailed description is given of the analysis of neutral kaons decaying to \pipi , based on the complete data sample collected with the CPLEAR experiment.Using a novel approach involving initially strangeness-tagged \kn\ and \knb ,the time-dependent decay rate asymmetry has been measured. This asymmetry, resulting from the interference between the \ks\and \kl\ decay amplitudes, has enabled both the magnitudeand phase of the CP-violation parameter, \ita , to be measured, with aprecision comparable to that of the current world average values.
