Nuclear Interactions Of High Energy Protons In Nuclear Emulsion PDF Download

Inelastic nuclear interactions in nuclear emulsions exposed to 200, 300 and 400 GeV proton beams are investigated. Dependence of inelastic cross sections on A is discussed. It seems to have been generally accepted that N{sub h}-distribution has little dependence on incident energies, but it is shown that the fraction of events without heavily ionizing tracks (N{sub h}=0) increases appreciably with increasing primary energies. Classifying events by number of heavily ionizing particles, the pseudo-rapidity distributions are studied, and the number of shower particles at higher rapidity region is less in central collisions with heavy nuclei compared to that in collisions with small N{sub h}.
