[en] The deviation of experimental data on the cross sections of deuteron fragmentation into protons on ¹²C at different energies with the calculated ones on the known two-nucleon wave functions is analysed. The similarity of the deviations is interpreted as the manifestation of the deuteron nonnucleon degrees of freedom at small distances. It is shown that the hybrid model describes the experimental data on the cross section of the deuteron fragmentation on ¹²C. The relativistic effects are taken into account in the framework of the light-cone dynamics
