On the possibility of particle beam bending or cooling by channeling in monocrystals

Some aspects of the particle beam deflection or cooling by means of channeling in single crystals are considered. An approximate formula for coefficient of particle capture to channeling regime is derived for the case of a bent single crystal. Recoil nuclei energy at channeling of particles is calculated in the approximation of quasifree atoms of a single crystal, and the influence of this energy losses on the character of particle motion is determined. The temperature dependence of the recoil nuclei energy and conditions for observing the transition from channeling, accompanied by atomic stopping losses, to unrecoiled channeling at a single crystal cooling are discussed
