A new decay channel emerges, in which a Rydberg atom relaxes to the ground state by transferring its excess energy to a weakly bound electron in the environment that is emitted from the cluster. We find evidence for this process in the electron spectra, where a peak close to the corresponding atomic ionization potential is observed. For Ar clusters, a decay time of 87 ps is measured, which is significantly longer than in previous time-resolved studies of interatomic Coulombic decay.enghttps://creativecommons.org/licenses/by/3.0/530Atomic beamsAtomsCondensed matter physicsDecay (organic)Ground stateInfrared devicesIonizationRydberg statesBound electronsDecay channelsElectron spectrumExcess energyInter atomic coulombic decayNear InfraredRydberg atomsTime resolved studiesIonization potentialArticleKonferenzschrift
