Developments in the semiclassical close-coupling description of atomic collisions, in an
energy range of roughly 0.1 up to a few hundred keV per nucleon of the projectile, are …

In this report we review, and put in context, the recent experimental and theoretical
developments generated by the use of particle and antiparticle beams in exploring the …

When an atom is ionized by ion impact, the electron is ejected into a final continuum state of
a two-centre potential due to the Coulomb fields of the projectile and ionized atom. The …

The continuum-distorted-wave-eikonal-initial-state model is extended to describe single-
electron ionisation by impact of bare projectiles on multielectronic targets. Applications are …

Publisher Summary The chapter focuses on the multielectron transitions in high-velocity
atomic transitions—that is, multiple ionization, electron transfer, excitation, and …

Data and analysis for the ratio of double to single ionization in helium is reviewed for impact
by photons and charged particles. In the case of photoionization there are two processes …

Single and multiple ionization of He, Ne, and Ar has been studied experimentally by impact
of fast protons and antiprotons. The single-ionization cross sections obtained with protons …

Measurements of the cross sections for single and double ionization of helium as well as for
the creation of H 2+ and H+ ions from H 2 for impact of antiprotons in the energy range 13 …

The single-ionization cross sections sigma+ for positron impact on H 2, He, Ne and Ar have
been measured from the ionization threshold to the high-energy region where the positron …

The four-particle process of proton-helium transfer ionization has been studied using cold
target recoil ion momentum spectroscopy to measure the momenta of all three particles in …
