General features of the reaction. pi. /sup +/p. --> delta. /sup + +/. pi. /sup 0/. pi. /sup 0/ at 8 GeV/c

Characteristics of the reaction ..pi../sup +/p..--> delta../sup + +/..pi../sup 0/..pi../sup 0/ at 8 GeV/c are presented. The sample consists of some 27, 000 events for which mass spectra, t-distributions, and ..pi pi.. angular distributions are presented. The ..pi../sup 0/..pi../sup 0/ mass spectrum rules out the ''narrow epsilon (700)'' solution for the ..pi pi.. S/sub 0/ phase shift. Data in the 1300 MeV region show substantial S-D wave interference.
