Abstract
We have unambiguously identified interatomic Coulombic decay in NeAr from the inner-valence double-vacancy state to outer-valence triple-vacancy states by momentum-resolved electron-ion multicoincidence. This is the first observation of interatomic Coulombic decay where three electrons () participate. The results suggest that this interatomic Coulombic decay is significantly faster than other competing processes like fluorescence decay and charge transfer via curve crossing.
