Title

Time-Dependent Size Distribution of Xenon-Cluster Ions

Abstract

The evaporation of monomers following electron-impact ionization causes a significant enhancement of the intensity anomalies (‘‘magic numbers’’) in mass spectra of xenon clusters. The dissociation rates are measured on a microsecond time scale for clusters containing between 10 and 79 atoms. The highest dissociation probability, 99(1)%, is found for Xe57+, which is two atoms larger than a closed-shell icosahedral cluster. Each anomaly in the dissociation rates corresponds to an intensity anomaly (‘‘magic number’’) in the mass spectrum. Recent Monte Carlo simulations for Xen+, n≤30, are in full agreement with our experimental results.
