The Normalisation of the Experimental Triple Differential Cross Section of Noble Gas Atoms in Extreme Asymmetric Geometry

Abstract

Electron-electron coincidence experiments, usually known as (e,2e) experiments, are the most powerful tool to study the process of the electron impact ionizationl,2. Despite the extended activity in the field in the last years, the understanding of the process for targets heavier than H and He still presents many serious challenges for both, theoreticians and experimentalists alike. As far as the experiments are concerned, the challenge consists in (a) providing a large body of experimental data to explore the various zones of the Bethe surface3, (b) determining the absolute scale of the triple differential cross-section (TDCS).
