The interference between CP-conserving K-S and K-L --> pi(+)pi(-)pi(0) decay amplitudes was observed by studying the decay rate asymmetries between initial K-0 and (K) over bar(0) separately for the phase space regions E(CM)(pi(+)) > E(CM)(pi(-)) and E(CM)(pi(+)) < E(CM)(pi(-)) For the parameter lambda we found Re(lambda) = 0.036 +/- 0.010(stat.)(-0.003)(+0.002)(syst.) and Im(lambda) consistent with zero, leading to a branching ratio B = [4.1(-1.9)(+2.5)(stat.)(-0.6)(+0.5)(syst.)] x 10(-7) for the CP-conserving K-S --> pi(+)pi(-)pi(0) decay.
