“…Driven by the motivation mentioned above, numerous theoretical (see e.g. McGuire et al (1981); Hippler et al (1987); Lee et al (1992); Fiol et al (2001)) as well as experimental studies have been reported in the literature. A first experimental identification of the (e,e) contribution by exploited its threshold behavior by measuring the velocity dependence of total projectile ionisation cross sections.…”

Recoil-ion and electron momentum spectroscopy is a rapidly developing technique that allows one to measure the vector momenta of several ions and electrons resulting from atomic or molecular fragmentation. In a unique combination, large solid angles close to π Microccopes -the "bubble chambers of atomic physics" -mark the decisive step forward to investigate many-particle quantum-dynamics occurring when atomic and molecular systems or even surfaces and solids are exposed to time-dependent external electromagnetic fields.The present review concentrates on just these latest technical developments and on at least four new classes of fragmentation experiments that have emerged within about the last five years. First, multi-dimensional images in momentum space brought unprecedented information on the dynamics of single-photon induced fragmentation of fixed-in-space molecules and on their structure. Second, a break-through in the investigation of highintensity short-pulse laser induced fragmentation of atoms and molecules has been achieved by using Reaction Microccopes. Third, for electron and ion-impact, the investigation of twoelectron reactions has matured to a state such that first fully differential cross sections (FDCS) are reported. Forth, comprehensive sets of FDCS for single ionisation of atoms by ion-impact, the most basic atomic fragmentation reaction, brought new insight, a couple of surprises and unexpected challenges to theory at keV to GeV collision energies. In addition, a brief summary on the kinematics is provided at the beginning. Finally, the rich future potential of the method is shortly envisaged.2

“…These are: i) zero-degree projectile electron spectroscopy [1,19], and ii) projectile chargestate analysis used in one of two modes, either in a) singles measurements [2,4,32] or b) in coincidence with recoils [5][6][7]33]. Zero-degree Auger electron spectroscopy has been applied to both excitation and ionisation studies and requires that the projectile carry at least 3 or 4 electrons, respectively.…”

ABSTRACf. Recent investigations of excitation and ionisation in collisions of fast highly-charged projectiles with H2 and He targets have shown that effects due to projectile-electron -targetelectron interactions can be clearly identified. The interacting electrons, traditionally assigned only a passive screening role, are now seen to acquire a new dynamic role, contributing a significant part of the excitation cross section, measuring up to 60%, as in the case of K-shell projectile ionisation at collision energies of a few Me V lu. Experimental signatures for these dynamic, twocentre e-e interactions can be found in the observation of excitation thresholds, resonances and electron exchange processes, traditionally associated with excitation of ions by free electrons.Improved applications of the Born and Impulse Approximations have been successful in accounting for the new data. A brief account of these investigations is presented.
