Annotation
Charge state-resolved time-of-flight spectra were collected for 2.0 keV23 Na+ scattered from Au nanoclusters deposited on TiO2 (110). The neutral fraction of Na scattered from metallic Au is small /3/, but it is surprisingly high /50/ for small clusters. The results demonstrate that alkali ions couple to electronic states specific to the nanoclusters.
