Tracks produced by 5.7 Bev protons in nuclear emulsions were followed until they interacted with emulsion nuclei, and a mean free path of 35.6 plus or minus 2.4 cm was obtained. About 24% of the shower tracks were found to be protons, all of which emerged at angles less than 20 deg with the direction of the primary. The mean multiplicity of pion production was found to be 2.6 plus or minus 0.3, the coefficient of inelasticity 0.49 plus or minus 0.07, and the transperse momentum of pions 220 plus or minus 30 Mev/c. The angular distribution of the shower tracks was analyzed on the assumption that the pions were produced in a single collision system with a forward--backward symmetry in the center of mass reference franne. The mass of the particle with which the incident proton formed such a collision, was shown to have an upper limit of 1.08 plus or minus 0.15 proton mass units. Hence the meson production on an average could be considered as arising in a nucleon--nucleon Collision even with a complex target nucleus. The angular distribution of the pions in the C-system was found to be isotropic, within the limits of experimental errors. (auth)
