摘要
Electron-ion-ion coincidence momentum spectroscopy, a well-established tool to study the molecular-frame core-level photoelectron angular distribution, has been applied to investigate interatomic electronic decay processes in argon dimers Ar-2 after the creation of a 2p inner-shell vacancy. Some interatomic Coulombic decay (ICD) processes from an Auger-final dicationic state are identified from the coincidence measurement between the kinetic energy of the ICD electron and the kinetic energy release between Ar+ and Ar2+. The interatomic character of the dissociation processes into Ar+-Ar+ is also discussed. (c) 2006 Published by Elsevier B.V.
