Complete (e,2e) experiments with COLTRIMS — •Alexander Dorn — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Due to the unique versatility of the COLTRIMS technique the dynamics of atomic and molecular reactions involving all kinds of projectiles covering charged particle- and photon-beams can be explored in utmost detail. Here its application to the study of electron collisions is reviewed. Some exemplary experiments include the investigation of strongly correlated few-body coulomb systems in the continuum which are produced close to the single- or double-ionization thresholds. For ionization of diatomic molecules the collision dynamics is observed to depend on the molecular axis alignment. Furthermore, collisions embedded in intense laser pulses were studied. Finally the current endeavors to perform experiments for ionization by positron impact will be discussed.
