The substantial progress that has occurred during the 1990s in the field of electron-atom-
collision theory is discussed. We show how a solution of a small-model three-body problem …

The basic ideas of the B-spline R-matrix (BSR) approach are reviewed, and the use of the
method is illustrated with a variety of applications to atomic structure, electron–atom …

The past decade has seen extraordinary theoretical progress in the field of fully
kinematically resolved atomic electron-impact ionisation, and its closely related field of …

The distorted‐wave Born approximation (DWBA) has been one of the most successful
theoretical approaches for treating electron collisions with complicated atoms, and recently …

Single ionization of helium by 102 eV electron impact has been studied by measuring the
momentum vectors of all final-state particles, ie, two electrons and the He+ ion, with an …

The theoretical and numerical approach used in a recent publication describing a
nonperturbative treatment of ionization and simultaneous ionization plus excitation of helium …

Electron-impact ionization cross sections for helium are calculated using time-dependent
close-coupling theory. The total wave function for the three electron system is expanded in …

Low-energy (E 0= 65 eV) electron-impact single ionization of Ne (2 p) has been investigated
to thoroughly test state-of-the-art theoretical approaches. The experimental data were …

Abstract Recently, Lahmam-Bennani et al (2010 J. Phys. B: At. Mol. Opt. Phys. 43 105201)
have shown that the second Born approximation is necessary to describe the experimental …

We develop a theoretical model to describe simultaneous ionization excitation and double
ionization of a two-electron atomic shell (ie, He 1 s 2) by a fast charged-particle impact. The …
