Scattering of Antiprotons by Nuclei (Atoms) in the Range of Low Energies Elesssim 10⁵ eV. Mirror Reflection, Diffraction, and Channeling of Antiprotons in Crystals

Studying antiproton scattering by nuclei (atoms) in the range of low energies, we found out that the increase in the antiproton-nucleus scattering amplitude through Coulomb interaction provides the possibility to investigate spin-dependent processes accompanying the interaction of antiprotons with nuclei (polarized or unpolarized) by means of mirror reflection of antiprotons from the vacuum-matter boundary, diffraction and channeling (surface diffraction and channeling) of antiprotons in crystals.
