Deflection of positively charged heavy particles by the crystal miscut surface

The motion of relativistic nuclei which move near to a crystal surface was considered. The nuclei within a beam penetrate the crystal field at the small angle to the crystallographic planes, so the average field approximation and channeling phenomenology are valid. The crystal surface has a specific terrace-like form. It was shown the significant beam fraction could be deflected outwards from the surface due to quasichanneling
