Production of π- -mesons in collisions of nucleons and light nuclei (d, α, C) with carbon nucleus at the momentum 4.2 A GeV/s

New experimental data on characteristics of the π-- -mesons produced in interactions of nucleons and light nuclei (d, α, C) with carbon nucleus at momentum 4.2 A GeV/s are presented. It is shown that growth of average meanings of momentum, longitudinal rapidity and reduction of emission angles of π-- -mesons are related to decrease of the contribution of the relative share of the pions produced in repeated collisions of nucleons of a projectile nucleus with nucleons of a target nucleus.
