We have used the polarized proton beam at the Argonne zero-gradient synchrotron to measure left--right asymmetries in the processes p/sub pol/ + p ..-->.. ..pi../sup + -/ + X at P/sub 0/ = 6 and 11.8 GeV/c and x = 0.1 to 0.9, where x is defined as p/sub l/*/P/sub max/*. For both pion charges, the asymmetries show considerable but different structure in u, the square of the four-momentum transfer between the incident proton and the outgoing pion. The data suggest that pions produced at large x in pp collisions results from a baryon-exchange process. (AIP)
