A relativistic microscopic model of collisions of nuclei which takes into account the internucleon forces is proposed. The model describes all the basic processes that take place in the collisions: motion of the Lorentz-contracted nuclei prior to the collision, formation of the compound system, propagation of the excitation over the nuclear matter, and disintegration of the system into fragments, including pions and complex nuclei. The calculations are carried out for the following cases: /sup 20/Ne(800 MeV/nucleon)+/sup 20/Ne, /sup 40/Ar(800 MeV/nucleon)+/sup 40/Ar, and ..cap alpha..(4 GeV/nucleon)+/sup 208/Pb. The model gives a satisfactory description of the experimental inclusive doubly differential cross sections for production of pions, protons, and deuterons. On the basis of the calculations performed, the compression of the nuclear matter is evaluated for different mass ratios of the colliding nuclei. Collective excitations of the shock-wave type are investigated.
