Description

If a high-energy charged particle penetrates through a crystal having a small angle between its momentum and one of the main atomic axes, correlations between successive collisions of the particle with neighboring atoms may occur. Because of periodic arrangement in the location of atomic strings in crystal such orientational effect as planar channeling is possible. When high-energy charged particle moves in a crystal having a small angle between its momentum and one of the main crystal atomic planes the motion of particle in many cases is determined by the continuous potential of atomic planes. The existence of continuous potential leads to the planar channeling of the particle in the field of neighboring atomic planes. In this work we investigate the influence of the periodicity of crystalline atomic strings arrangement on the spectral and spectral-angular distribution of high-energy charge particle radiation in crystal.
