3114 events of the reaction ..pi../sup +/d ..-->.. ..pi../sup +/..pi../sup -/pp/sub s/, where p/sub s/ is a nonparticipating spectator, were studied in the SLAC 82-inch bubble chamber. A longitudinal-phase-space (LPS) analysis was performed to separate the various t-channel exchange mechanisms, e.g., ..pi.. or Pomeron exchange. The validity of the LPS method was tested for pion exchange by generating events using the one-pion-exchange model modified by absorption (OPEA). The model and the data agreed extremely well. The principal features of the data include the rho/sup 0/, f/sup 0/, ..delta../sup 0/, and N*'s. The LPS analysis also reveals the g/sup 0/, but a slight modification of the standard LPS selection criteria enhances the g/sup 0/, as expected by OPEA-model calculations.
