A 970 Mev proton beam has been passed through a hydrogen-filled diffusion cloud chamber located in a pulsed magnetic field, and a total of 1029 proton-proton interactions observed. The cross sections for the possible reactions, and the angular distribution for the elastic scattering, have been determined. The effects of scanning losses on these quantities are discussed The results from 273 events of the type p + p yields n + p + pi /sup +/, and 72 events of the type p + p yields p + p + pi /sup 0/, have been calculated in detail. They are compared with the predictions of the 'isobar' theory of pion production in which it is postulated that the production of pions occurs through an intermediate state of isotopic spin T = 3/2. The results for positive pion production are in good agreement with this hypothesis, and disagree markedly with the predictions of a purely statistical theory. The results for neutral pion production do not agree well with the predictions of the isobar theory. (auth)
