The analysis was performed for energy attainable at CERN accelerators. The analysis showed that for positively charged particles the probability of close collisions at the stochastic deflection particles much smaller than in the planar channeling. Results found that the probability of negatively charged particles of pi-mesons minus close collisions at the stochastic deflection twice this same probability for planar channeling. The analysis of the possibility of output antiproton beam from HESP GSI rings with kinetic energies up to 10 GeV bent crystal was done. The analysis showed that the most effective of the basic mechanisms of deflection of charged particles in a bent crystal, characteristic for a given accelerator complex, there is a stochastic mechanism deflection. The obtained results show that this mechanism makes it possible to deflect most of such energy antiproton beam at an angle that is equal to 1 mrad. In planar channeling under the above conditions only a small part of the beam particles deflected by an angle of bending of the crystal as well the volume reflection allows deflect antiprotons at very small angles.
