The NA48 Collaboration has measured the amplitude of the CP-conserving component of the decay KS0→π+π -π0 relative to KL0→π +π-π0. For the characteristic parameter λ, the values Reλ=0.038±0.010 and Imλ=-0. 013±0.007 have been extracted. These values agree with earlier measurements and with theoretical predictions from chiral perturbation theory.
