A generalization of the one-pion exchange model for the reaction pi -p - - pi /sup +/ pi /sup -/n in the resonant pi pi region is developed by means of the five-point function of Bardakci and Ruegg. The model, using the slope of the pion trajectory as the only adjustable parameter, has appropriate spin content and proper Regge behavior. A K-matrix unitarization scheme for mesons, generalized for the production process, was used. The model is applied over a wide range of energies, and variations of all four remaining independent variables are also examined. The results are in general agreement with experiment, suggesting that the formulation is a desirable improvement over previous phenomenological models. (auth)
