Abstract

The production of

Δ^{+ +} (1232)

is investigated inclusively and semi-inclusively, and is compared with that of protons. We find differences in the Feynman

x

distributions for

Δ

's and protons near

x = - 1.0

, which can be attributed to different exchange contributions in these processes. It is found that not all

Δ^{+ +}

come from the diffractively excited target proton. Density matrix elements of the

Δ^{+ +}

are in agreement with the predictions of the one-pion-exchange model with absorption.
