OMEGA AND ETA PRODUCTION IN PI+D-]PPPI+PI-PIO AT 3.65 BEV/C

We have observed ∼3000 examples of the reaction π+d→ppπ+π-π0 and report on ∼300 events in which the π+π-π0 mass is in the ω0 mass region and ∼40 events in the η0 mass region. Differential cross sections are presented. There is evidence for a backward peak in the overall channel. We give values for the ω0 density-matrix elements in the forward direction. Our value for Reρ10 is negative, in disagreement with various theoretical models. © 1969 The American Physical Society.
