Abstract

Collisions between 12C nuclei and a beryllium target at energies of 0.3–2.0 GeV/nucleon are considered for carbon nuclei with proton emission at an angle of 3.5°. It is shown that such experimental data obtained in the Institute for Theoretical and Experimental Physics (ITEP) on proton spectra can be described in terms of a hydrodynamic model for the high-energy cumulative region of the proton spectrum with allowance for the contribution from ion fragmentation for the soft spectral region in terms of the statistical fragmentation model.
