Abstract
A study of a 150000-picture exposure of ¯pd at 5.5 GeV/c yielded 152 events satisfying the hypothesis ¯pd→p s π+2π−π0. For the events with proton spectator in the momentum range 100–280 MeV/c we obtained the cross section of 0.11±0.02 mb. Assuming the validity of the impulse approximation we estimate a cross section of 0.43±0.06 mb for the reaction ¯pn→ π+2π−π0. The rate for single ϱ meson production and an upper limit for double ϱ production are given. A modified multiperipheral Regge model was used in order to describe the general features of the data.
