Triple scattering of electrons

In this thesis scattering experiments of relativistic electrons from heavy atoms are described. The main attention given to a new type of experiments in which electrostatically accelerated electrons experience three subsequent scattering events on gold targets. A justification for this type of so-called triple scattering experiment may be found in the Introduction (Chapter I) and in Chapter II, section 2. In chapter II a cursory description of the theory of of electron scattering is given, the main purpose being the definition of the various parameters in electron scattering and the description of the relation of our experiments to other experiments in this field, i.e. double scattering experiments and measurements of the differential cross-section. The last part of Chapter II contains a short review of the present situation of theory and experiment, which reveals the existence of some unsolved discrepancies.
