The ITEP experimentaldata on the emission of protons, pions, and photons in collisions of 12С nuclei with a beryllium target at energies of 2.0 and 3.2 GeV/nucleon are considered. It is demonstrated that these data can be uniformly described within the framework of a nonequilibrium hydrodynamic model for the high-energy cumulativeregion of a proton spectrum with consideration for the contribution from the fragmentation of ions for the soft region of the spectrum within the statistical fragmentation model, as well as for cumulative pions and photons.
