Abstract :Abstract: The available experimental data point to the absence of the energy interval of scattering. This makes a basis for the hypothesis about the existence of a non-zero polarization research on the future accelerators will provide information about the structure of the nucleon interaction at large distances. Using different hypotheses about the property of the nucleon interaction at large distances a number of model approaches lead to the nondisappearing polarization in high -energy processes at small transfer moment. In this investigation we regard the model results for the polarization effects of nucleon-nuclei scattering.  In the framework of the hypothesis concerning the exis¬tence of quark bag in nuclei we managed to describe the behaviour of the formfactors of nuclei at large q and structure functions of nuclei. The parameters of quark distribution in the bag at k>>k0 (the parameter k0 may in principle be different for different bags) extracted from the data on formfactors and on deep inelastic scattering of nucleons on nuclei proved to be very close. This result allows us to suppose that the contribution of the nucleon to the main terms in the spin-flip amplitude. The hypothesis will be proved in this work. The analysis shows that when the preasymptotic corrections are absent, we have the zero polarisations. The parameters in the spin-flip amplitude determined from one reaction, for example nucleon-nuclei scattering, allow us to obtain a wide circle of results for the polarisation effects of elastic pp or meson-nucleon scattering at high energies.
