Over the past two decades impressive progress has been made in the theoretical and the
experimental study of the multiple excitation and of the complete fragmentation of four-body …

We investigate single-photon double ionization of H 2 by 130 to 240 eV circularly polarized
photons. We find a double slitlike interference pattern in the sum momentum of both …

Deep minima in He (e, 2 e) He+ triply differential cross sections are traced to vortices in
atomic wave functions. Such vortices have been predicted earlier, but the present …

Vortices are usually associated with systems containing large numbers of particles. Of
particular topical interest though are those formed within atomic-scale wave functions and …

We investigate ionization of atomic hydrogen by electron-and positron-impact. We apply the
Coulomb–Born (CB1) approximation, various modified CB1 approximations, the three body …

Through the description of several simple atomic-scale systems for illustration, the
hydrodynamical interpretation of results of solving the time-dependent Schrödinger equation …

The presence of vortices in the ionization of hydrogen atoms by positrons at intermediate
impact energies is investigated. The present findings show that a previously reported …

The three-Coulomb wave (3C) model is applied to study single ionization of helium by 75
keV proton impact. Fully differential cross-sections (FDCS) are calculated in both the …

The time-dependent close-coupling method and a distorted-wave approach are used to
explore deep minima discovered in the non-coplanar triple differential cross sections for the …

Following the work of Berakdar (1996 Phys. Rev. A 53 2316), momentum correlation in the
three-body Coulomb continuum problem is considered by the introduction of effective …
