Relaxation processes following 1s photoionization and Auger decay in Ne2

We used cold target recoil ion momentum spectroscopy for a comprehensive study of the decay of a neon dimer (Ne-2) after removal of a 1s electron from one of the atoms of the dimer. Multiple decay pathways are found and identified, mostly being connected to different types of interatomic Coulombic decay (ICD) such as the direct ICD which happens via the transfer of a virtual photon, the exchange ICD via an electron transfer and the electron transfer mediated decay. A quantitative theoretical analysis of these decay processes can be found in the preceding paper by Demekhin [Phys. Rev. A 78, 043421 (2008)], as well as in Stoychev [J. Chem. Phys. 129, 074307 (2008)].
