Results are presented from an experiment in which high-energy deuterons, produced by proton-proton interactions at 21.1 GeV/ c incident momentum, were detected over a range of angles from 12.5 mrad to 60 mrad in the laboratory system. From the momentum spectra of the deuterons, the final states D + π + and D + ϱ + have been identified. The angular distribution for these reactions are presented and compared with previous data at lower energies.

The differential cross section for the process p+p→π++d was measured at 5.0 GeVc for a center-of-mass angle of 90°. The experiment was done on the Argonne ZGS with the same apparatus as was used in a recent 90° proton-proton elastic scattering experiment. The extracted proton beam of the ZGS was made to impinge upon a CH2 target. The pion and deuteron were detected by two spectrometers, each containing magnets and a scintillation-counter telescope, in coincidence. The incident beam flux was measured by a radiochemical analysis of the CH2 target. The 90° cross section at 5.0 GeVc was found to be 35±9 nb/sr.
