Work function of the sample shown as a function of Au deposition.
TOF spectra of the total and neutral yields collected at a 150° scattering angle for normally incident scattered from 0.32 ML Au deposited on . The dashed lines indicate the backgrounds used in the analysis, and the integration areas are shaded.
Neutral fractions of ions singly scattered from (a) Au and (b) Ti shown as a function of the average Au coverage.
Neutral fractions of ions scattered from (a) Au clusters and (b) Au foil, shown as a function of the exit angle with respect to the surface normal for the indicated coverage. The dotted line in (b) shows a calculation of the expected NF, and the filled square was collected with a incident energy. The solid lines are drawn to guide the eye, and a typical error bar is shown.
Neutral fraction of ions scattered from Au clusters shown as a function of the incident energy.
Comparison of neutral fractions for and ions scattered from Au on . Both were measured at normal incidence with a 150° scattering angle.
