Multiplicity, momentum and angular distributions of protons from the interactions ofp, d, α andC with carbon at 4.2 GeV/c/nucleon momentum

Average multiplicity of protons fromp, d, α andC interactions with carbon at 4.2 GeV/c/ N is shown to increase with the mass number of incident nucleus. ThisA dependence is stronger for fast protons than for the slow ones. Angular and momentum distributions are described by the Dubna Cascade Model. Some discrepancy is observed in the high momentum part of the distributions.
