WebAbstract. Ion-atom collisions have been of interest to the general physics community because of their relevance to the penetration of charged particles in matter. As fast, charged ions pass through matter they ejected electrons from the atomic constituants. These electrons initiate physical and chemical changes known as radiation damage. WebInteractions of photons and electrons with atoms, molecules, and ions are fundamental elementary processes in a wide variety of neutral or ionized gases in nature or laboratory. The data on the cross sections or related quantities for those processes are eagerly …
