摘要

Polycrystalline Ag, Ag_(20)Au_(80), Ag_(40)Au_(60), Ag_(80)Au_(20) and Au samples were bombarded with 15 keV Ar~+ at 60° incidence and the resulting secondary neutral yield distribution was studied by non-resonant laser postionisation mass spectrometry. Neutral clusters containing up to 21 atoms were observed for the targets. The yield of neutral clusters, Ag_mAu_(n-m), containing n atoms, Y_n, was found to follow a power in n, i.e. Y_n ∝ n~(-δ), where the exponent 8 varied from 3.2 to 4.0. For a fixed n, the cluster yields showed a variation with number of gold atoms similar to that expected for a binomial distribution. In addition, the cluster compositions from the sputtered alloys were indicative of sputtering from a gold rich surface.
