Abstract : A sample of 133 interactions in nuclear emulsions initiated by 26.7 Gev/c protons was examined. It was found possible to separate the events fairly well into two groups, one in which almost all of the shower particles were emitted in a single nucleon-nucleon collision in a target nucleus, the other (cerca 20%) in which the shower particles were produced in two or more successive collisions in a target nucleus. Analysis of the effective target mass distribution of the events and the (log cot theta) distribution, where theta is the laboratory emission angle of a shower particle, supported the above interpretation and indicated that an appreciable fraction of the events in the first group might be attributed to peripheral nucleon-nucleon collisions.
