Abstract

The characteristics of leading pions and other pions in 11-GeV ..pi../sup -/p interactions in the CERN two-meter hydrogen bubble chamber are investigated. It is shown that the bend in the integral momentum spectrum shifts toward the lower momentum values with increasing multiplicity. The average emission angle of the leading pions is weakly multiplicity dependent. The dependences of the average transverse momenta and energies of the leading pions and the other particles on the number of produced pions are found experimentally.
