ANGULAR-DISTRIBUTIONS OF CHANNELED PARTICLES

The paper describes angular distributions of channeled particles in th ick single crystals. II is shown that the distribution of channeled pa rticles over the angles may be calculated if the statistical equilibri um in the transverse phase space lakes place. The results obtained in computer simulation are compared with analytical calculations for axia lly channeled electrons. It is shown, that due to the influence of the continuum string potential the angular distribution in the oriented c rystal becomes essentially broader then one in an amorphous medium.
