Ion-Atom Collisions,r. As fast, charged ions pass through matter they ejected electrons from the atomic constituants. These electrons initiate physical and chemical changes known as radiation damage. For this reason the spectra electrons ejected by fast, positively charged ions have been of studied from the early days

Ionization in Time-Dependent Processes: Proton-Hydrogen Collisions,Ion-Mass-Spectrometry (COLTRIMS) imaging technique has been used to obtain energy and angular distributions of electrons ejected from atoms in a variety of atomic processes.. Distributions of electrons produced by slow ion-atom collisions are of particular interest since there is as yet no consensus

Optics and Interferometry with Atoms and Molecules,by Young, Fizeau, Michelson-Morley and others. Quantum mechanics, and especially the deBroglie’s postulate relating the momentum . of a particle to the wave vector . of an matter wave: . = 2π/λ = ./?, suggested that wave optical experiments should be also possible with massive particles (see table 1

Negative Ion Resonances in Surface Dynamics: New Results and Applications, phase. and in adsorbed or condensed phases. .,. The negative ion resonance (NIR) scattering mechanism is a short range scattering event in which the scattered electron is temporarily trapped in an unoccupied anti-bonding orbital of the target molecule, leading to the enhancement of the vibrational

Atomic Collisions with Antiparticles,ween fundamental charged projectiles and simple atoms allows us to investigate the dynamic many-body problem under very well defined conditions. If, for example we regard the ionization of a hydrogen atom by impact of an antiproton, we start with a bound system which is accurately described, and end

Near Threshold Electron Impact Ionization of Neon and Argon,out electron impact ionization of atoms is available from (e,2e) experiments in which both electrons following an ionizing event are detected in coincidence. The kinematics of the collision is then fully determined and provides the measurement of triple differential cross sections (TDCS). In the pas
