Vysotskyy M. Peculiarities of coherent and nonlinear processes at interaction of the moving charged and neutral particles with the ordered media

Conditions and characteristics of coherent channeling mode existence are considered, coherency influence effect on motion and radiation of particles in crystals is found. In particular, in this mode the increase of radiation probability and beam angular diagram narrowing can be observed. Parametrical processes at particles channeling are considered. Peculiarities Doppler effect for moving particles in the environment with a dispersion at the account of recoil effect are studied. Features of the radiation of relativistic particles under Cherenkov resonance conditions are considered. Mechanisms of orientational interactions of neutral particles with crystal planes, superlattices, atoms and nuclei are considered.
