Non-local decay mechanisms play an important role in the relaxation of electronic vacancies in dense media such as biological samples. To explore these mechanisms in a less complex environment, rare gas clusters can be used as a prototype system for experiments. The use of multi-coincidence spectroscopy enables the detection of core-level Interatomic Coulombic Decay (ICD), which is a comparatively weak process in relation to the local Auger decay followed by Radiative Charge Transfer (RCT). Here, we present the observation of changes in ICD efficiency when going from homogeneous Ar and Kr clusters to heterogeneous ArKr clusters and thereby introducing a different environment to the excited atom in the respective cluster.
