Résumé : 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{variant}+ have been identified. The angular distribution for these reactions are presented and compared with previous data at lower energies. © 1969.
