摘要

The work is devoted to the implementation of the hydrodynamic laws to the head-on heavy ion collisions within the energy range 50-100 MeV/A.The hydrodynamic mechanisms of the bubble and ring structures formation are investigated.It is shown that there is a possible hydrodynamic explanation of the different structures being formed in the case of soft(K=200 MeV) and stiff(K=400 MeV) equations of state.Within the suggested approach the final geometry of the system is defined in the initial stage of the collision and is very dependent on the sound velocity in the nuclear matter.The obtained results are in a good correspondence with the Boltzmann-like transport theory calculations and the experimental data for the selected energy range.
