[en] The results on the energy spectra of g-particles investigations obtained in the interaction of ¹²C relativistic nuclei at 54 GeV/c with nuclear emulsion are presented. It is shown that the average energy of protons emitted at a fast stage of the process increases with the growth of the incident particle mass. It has been found that the decrease of the impact parameter of interacting nuclei makes the spectrum of fast protons harder. The energy of b-particles increases as well. It is noted that the obtained peculiarities of the g-particle energy distributions are difficult to explain within the frameWork of the usual superpositional model. Within the statistics, the obtained data can point to the appearance of the effects of collective nucleon collisions of interacting nuclei
