Enhanced charge transfer in doped nano-systems measured via electron-ion coincidence technique

Interatomic energy and charge transfer in a Xe doped Ar cluster have been investigated. Besides interatomic Coulombic decay (ICD), electron transfer mediated decay (ETMD) seems to play a significant role in the relaxation process of heterogeneous systems which is in strong contrast to pristine clusters. Ar 2p electrons have been measured in coincidences with cluster fragments. The high resolution in time and energy of the detectors enabled us to determine the site of ionization on the cluster and the kind of the resulting fragments.
