Abstract

Proton-induced pion production to the continuum was investigated via the reactions C13(p,π)X, C13(p,π+)X, and O16(p,π+)X at bombarding proton energies of 250, 354, and 489 MeV, in the kinematic region where the pion has nearly its maximum allowable kinetic energy. Results from the O16(p,π+)X reaction indicate that at small missing momenta the analyzing powers can be adequately described by a quasi-free p→p→dπ+ process, but as the missing momentum is increased this description becomes less accurate. The energy dependence of the cross section for the inclusive (p,π+) reactions is very similar to that of previously published exclusive (p,π+) data from the same target nuclei. The double differential cross sections for the π data, however, exhibit an energy dependence different from that of the exclusive (p,π) reaction.
