We present in this paper a study of the ..delta../sup + +/(1232) inclusive production for momentum transfer squared to the target proton, vertical-bartvertical-bar < 1 (GeV/c)/sup 2/. We have investigated the production mechanism of the ..delta../sup + +/ by measuring its density matrix elements as a function of t and of the missing mass squared, M/sub X//sup 2/, and by carrying out a triple-Regge analysis. For vertical-bartvertical-bar < 0.4 (GeV/c)/sup 2/, the ..delta../sup + +/ production mechanism is consistent with one-pion exchange. We have also studied the average charged multiplicity recoiling from the ..delta../sup + +/ as a function of M/sub X//sup 2/, for vertical-bartvertical-bar < 0.4 (GeV/c)/sup 2/. The study yields information about the ..pi../sup -/..pi../sup -/ average charged multiplicity.
