The atomic hydrogen target has played a pivotal role in the development of quantum
collision theory. The key complexities of computationally managing the countably infinite …

The present state of the theoretical study of ionization in ion–atom and atom–atom collisions
is reviewed on the basis of quantum mechanical approaches to the solution of the time …

In this work, we develop a wave-packet continuum-discretization approach to ion-atom
collisions that includes rearrangement processes. The total scattering wave function is …

A general single-center close-coupling approach based on a continuum-discretization
procedure is developed to calculate excitation and ionization processes in ion-atom …

Details of the recently developed quantum-mechanical two-center convergent close-
coupling approach (Abdurakhmanov et al 2016 J. Phys. B: At. Mol. Phys. 49 03LT01) to …

A method for solving the time-dependent two-center Dirac equation is developed. The time-
dependent Dirac wave function is represented as a sum of atomiclike Dirac-Sturm orbitals …

We report on double and single differential cross section measurements of the 1 s 2 s 2 S 2,
1 s 2 s 2 p P±2, and 1 s 2 s 2 p P 4 doubly excited states produced by single-electron …

Wavepacket continuum-discretisation approach is used to calculate excitation, ionization
and electron-capture (ec) cross sections for proton collisions with n= 2 states of atomic …

The semiclassical convergent close-coupling approach to ion-atom collisions has been
extended to include electron-transfer channels. The approach has been applied to study the …

We present measurements and calculations of the momentum distribution of electrons
emitted during the ion-atom collision 10 keV/u He 2++ He→ He++ He 2++ e−, which show …
