The SLAC 40-inch bubble chamber augmented by an array of lead-glass detectors was used to study the reaction ..pi../sup +/p..--> delta../sup + +/..pi../sup 0/..pi../sup 0/ at 15.7 GeV/c. No new high-mass neutral mesons are seen at a sensitivity of 14.2 events/..mu..b. A moments and amplitude analysis indicates that only S and D waves contribute to the ..pi../sup +/..pi../sup -/..--> pi../sup 0/..pi../sup 0/ cross section. A one-pion-exchange-model calculation is performed using phase-shift measurements from other experiments. The older phase shifts from Estabrooks and Martin are in better agreement with our data than are the more recent ones of Biswas et al.
