Auger decay of Ne 1s photoionization satellites studied by a multi-electron coincidence method

Abstract

The Auger decay of Ne 1s photoionization satellite states is studied with a magnetic-bottle multi-electron coincidence method. The energy correlations among the multi-electrons associated with the double Auger decay from the Ne+ satellite states are extracted from the accumulated coincidence dataset. It is concluded that the Ne2+ states populated through the initial Auger decays from the Ne+ satellite states can be excited states that lie above the Ne3+ threshold. Their subsequent decay produces slow electrons in the 0–25 eV kinetic energy range. Possible assignments of the intermediate Ne2+ and the final Ne3+ states are given.
