Atomic processes of high energy heavy ions channeled in a crystal

Abstract

Swift heavy ions channeled in a crystal experience a variety of atomic processes which depend on the ion trajectory in the channel. Recent studies on the atomic processes such as slowing down of the ion, charge changing collision, excitation of bound electrons, and so on in connection with ion trajectories or impact parameter are reviewed. Resonant coherent excitation (RCE) is a composition of various atomic processes and has offered a new field in atomic physics and has been investigated experimentally and theoretically. Recent progress in this field is also reviewed.
