Abstract [en]

Auger electron lineshapes after electron impact inner-shell ionization of argon at 500 eV primary electron energy are studied by the (e, 2e) coincidence technique. Emitted Auger electrons are detected in coincidence with the ionizing scattered electrons and the energy of the slow PCI inducer ejected electron is calculated from energy conservation. In particular, the strongly asymmetric energy sharing, and by this means the effect of the very low energy (i.e. 0-5 eV) ejected electrons, is measured and compared with calculations. The opposite case (equal energy sharing) is also studied.
