Statistics of projectile states and correlated phenomena for penetrating ions

Abstract

The first part of the paper summarizes a recently developed formalism for the statistical description of projectile-state-dependent penetration phenomena. The central point is a generalization of the Bothe-Landau scheme governing multiple scattering and stopping under the condition of small relative energy loss. Tools are listed that may be employed in the theoretical analysis and reference is made to recently published applications. The second part reports new applications which include i) charge-dependent multiple scattering, in particular the transient behavior after few charge exchanges, and ii) expressions for the energy-loss spectrum under similar conditions. Comments are made on iii) the interference of charge exchange and energy loss in a multicomponent material and on iv) fast pre-equilibrium charge states observed for heavy ions penetrating thin films.
