Interatomic Coulombic decay and electron-transfer-mediated decay following triple ionization in Ne2, NeAr, and Ar2

Abstract

We report the first observation of electron-transfer-mediated decay (ETMD) and interatomic Coulombic decay (ICD) from the triply charged states with an inner-valence vacancy, using the Ne2, NeAr, and Ar2. These ETMD and ICD processes are unambiguously identified by electron-ion-ion coincidence spectroscopy in which the kinetic energy of the ETMD or ICD electron and the kinetic energy release between the two fragment ions are measured in coincidence. © Published under licence by IOP Publishing Ltd.
