Elasti c and inelastic 19.8 Bev/c proton-proton collisions in nuclear emulsions are examined using an external proton beam of the CERN Proton Synchrotron. Multiple scattering, blob density, range, and angle measurements give the momentum spectra and angular distributions of secondary protons and pions. The partial cross sections corresponding to inelastic interacti ons having two, four, six, eight, ten, and twelve charged secondaries are found to be, respecti vely, (16.3 plus or minus 8.4) mb, (11.5 plus or minus 6.0) mb, (4.3 plus or minus 2.5) mb, (1.9 plus or minus 1.3) mb, (0.5 plus or minus 0.5) mb, and (0.5 plus or minus 0.5) mb. The elastic cross section is estimated to be (4.3 plus or minus 2.5) mb. The mean charged meson multiplicity for inelastic events is 3.7 plus or minus 0.5, and the average degree of inelasticity is 0.35 plus or minus 0.09. Strong forward and backward peaking is observed in the center-of-mass system for both secondary charged pions and protons. Distributions of energy, momentum, and transverse momentum for identi fied charged secondaries are presented and compared with the results of work at other energies and with the results of a statistical theory of proton-proton collisions.
