Abstract	Charged particle production (pi^{+-}-mesons and protons) in nucleus-nucleus interactions at the energy of 3.3-3.7 GeV/nucleon is considered. It is shown that the FRITIOF model adapted to moderate high energies reproduces the energy spectra of the mesons emitted into backward semisphere in the laboratory system, and their dependence on masses of the colliding nucleus. The FRITIOF model enlarged by the reggeon theory inspired model of nuclear destructure allows one to describe soft part of spectra of the backward flying protons. For a description of the hard part of the spectra it is needed to attract another approaches.
