The pi0 pi0 mass spectra and angular distributions around KKbar -thresholdand at 1.5 GeV in ppbar (at rest) --> 3 pi0 in the Crystal Barrel experimentare reanalyzed by applying the new method, which is consistent with unitarityof S-matrix and expressed directly by resonance parameters. The effects oflight sigma-meson production are clearly seen to improve the fit with sigma, incomparing with the fit without sigma.Comment: 8 pages, 1 Postscript figure, uses ptptex.st
