The expression for the most probable value of the IEL pair in the target is obtained. The review is carried out both using an approach that does not take into account the effects of the bound state of atomic electrons and is valid for targets of moderate thickness, and using a more rigorous approach that allows taking into account the mentioned effects and is valid also in much thinner targets. It is shown that in sufficiently thin targets, the most likely value of the pair's IEL can be noticeably more suppressed due to the Chudakov effect than the full or limited average value of the pair's IEL in the target. On the basis of the eikonal approximation of quantum electrodynamics, the possibility of the rainbow scattering effect during the movement of fast charged particles near the crystal plane of atoms was illustrated. Using the method of numerical integration, the differential scattering cross section for the specified problem was obtained. An approximate analytical expression for this cross section in the region near the rainbow point was also obtained. A range of target parameters is defined in which the effect should be observed and visible. Product Description popup.authors Bondarenko Mykola V. Kyryllin Igor Volodymyrovych Koriukina Viktorija D.
