New experimental data on π−-meson production in interactions between carbon and tantalum nuclei at amomentumof 4.2 GeV/c per nucleon are presented. These results are compared with predictions based of themodel of quark-gluon strings (QGS) that is adapted to intermediate energies ( $$ \sqrt 4 $$ ≤ 4 GeV). It is shown that the QGS model only qualitatively reproduces the behavior of experimental kinematical features of π− mesons.
