Abstrakt: We report on results of an experiment to study the reaction p-p ? p- p+ in the incident pion momentum region between 295 and 450 MeV/c. A departure from phase space was observed in invariant-mass spectra and angular distributions which cannot be explained with ? and ? resonance production. It indicates aI=0,JP = 0+ p- p+ final-state interaction.
