Abstract
About 100 million events of proton-antiproton annihilation into all-neutral final states have been used to extract the partial waves for the final sta tes ww, w eta and w pi (0) for various momenta in steps of about 150 MeV/c. The data has been taken by the Crystal Barrel experiment at LEAR in 1996. The total cross section and the partial wave decompositon have been determi ned from this dataset. It has been shown that an unambiguous decomposition is feasible, which is important for the investigations of forthcoming exper iments. Although dominant waves could be extracted, no significant resonant structures appeared unambiguously identified. This is due to the limited s tatistics available and the coarse binning of this investigation.
