In this combined experimental and theoretical work, we investigate the nature of charge-transfer processes in homogeneous atomic and heterogeneous atomic-molecular clusters. Our results reveal fundamentally different processes to be at play in pure argon clusters compared to mixed argon-nitrogen systems: We demonstrate that the former species decay via photon-mediated charge transfer while a nonradiative direct process is found dominant in the atomic-molecular cases. Our results are of general interest for studies on charge redistribution in more complex and biologically relevant samples where molecules are involved. 000002623 546__ $$aEnglish 000002623 6531_ $$aAtomic & molecular clusters 000002623 6531_ $$aAutoionization & Auger processes 000002623 6531_ $$aElectronic excitation & ionization 000002623 6531_ $$aInteratomic & molecular potentials 000002623 655__ $$aAtoms, molecules, clusters, and gas-phase chemistry 000002623 690__ $$aExternal experiment 000002623 7001_ $$aKüstner-Wetekam, C. 000002623 7001_ $$aHu, X.
