(various pagings) illus., tablesModels based upon pion-exchange and diffraction dissociation have been fitted to data from reactions of the type πˉp → Nucleon + kπ, 2 < k < 7 at 3.9 and 11.9 GeV/c incident momentum. These models, which include resonance production, give approximately correct mass- and t-distributions, as well as transverse and longitudinal components of momentum. Partial cross-sections for dominant channels have been estimated, and relations between cross-sections compared with theoretical predictions.en-USAll UHM dissertations and theses are protected by copyright.
