An overview of the current status of perturbative theoretical approaches to charge in
energetic ion-atom collisions is presented. One of the main aims of the article is to provide a …

Scattering is one of the most powerful methods used to study the structure of matter, and
many of the most important breakthroughs in physics have been made by means of …

Publisher Summary This chapter discusses the continuum distorted wave method in both
time-dependent and time-independent form and presents the clarification of its physical …

A model is developed where the implicit continuum intermediate states are approached by
Coulombic phases (such that the correct boundary conditions are satisfied) in electron …

Single charge-exchange in collisions of heavy bare nuclei with the ground state of two-
electron atomic targets is described perturbatively as a four-body problem. The employed …

A unified description for anisotropic near-threshold excitation in terms of statistical O (4)
multipoles is presented. It is shown that a single set of multipole parameters can …

Explicit expressions for capture of an electron to and from arbitrary hydrogenic states are
presented for various multiple-scattering approaches, namely approximate forms of the …

We perform an extension of the continuum-distorted-wave (CDW) approximation for single
electron capture by introducing model potentials to describe the interaction of the active …

The differential cross section (DCS) for electron capture at asymptotically high, but non-
relativistic, energy is investigated within the second-order distorted-wave approximation …

Total and differential cross sections for excitation are calculated using three distorted-wave
methods: the continuum distorted-wave (CDW) method, the Coulomb peaking impulse …
