Abstract: Observation of antiproton--proton collisions in a propane bubble chamber at an average energy of 120 Mev has been accomplished. The ratio of antiprotons to other particles in the beam has been increased by utilizing the differential rate of momentum loss in absorbers between antiprotons and other particles. The angular distribution of 33 p-p scattering events between 15 and 165 deg c.m. is presented. (W.D.M.)
