Description of Fragments Emitted in Collisions of Intermediate-Energy Heavy Ions Using a Nonequilibrium Hydrodynamic Approach

A nonequilibrium hydrodynamic approach was used to describe the experimental data obtained at the Alikhanov Institute of Theoretical and Experimental Physics on double differential emission cross sections of 11Be and 12B nuclei at an angle of 3.5° in the reaction 12С + 9Be → f + X at an energy of 300 MeV per nucleon for incident carbon nuclei. A comparison with other models was made, and the dynamics of the fragmentation process was analyzed.
