Analyzing Power in the Reactions p + d → d + p and p + p → d + π at GeV Energies

We have used a polarized proton beam to measure the analyzing power for pd backward elastic scattering at incident kinetic energies of 0.68, 1.03, and 1.53 GeV and for the reaction p + p ..-->.. d + ..pi.. at 1.03 GeV. The data indicate that several mechanisms dominate pd backward elastic scattering over this energy range.
