摘要：

A sample of 1147 events of the type π-p→π-π0p has been obtained from the measurement of 30 400 two-prong events in an exposure of the Brookhaven 80-in. hydrogen bubble chamber to an 8-GeV/c π- beam. In the π-π0 system, the ρ- and g- mesons are observed; neither is strongly associated with isobar production. The presence of appreciable ω0 exchange in π-p→ρ-p is suggested by the shape of the Δ2 distribution in this reaction and by the ratio of the production cross sections σ(π-p→ρ0n)σ(π-p→ρ-p) at 8 GeV/c. © 1969 The American Physical Society.
