In this paper, we investigate the global structure of mixed
clusters created by coexpansion. To determine the relative dopant
sites within the mixed clusters, we take advantage of the strong
dependence of the cluster/surface collision dynamics on the
incident mixed cluster structure. Using both experiments and
molecular dynamic simulations, we show that the coexpansion
process leads to the most stable cluster structure for
clusters. This structure
corresponds to an annealed structure and can be characterized as a
nearly homogeneous mixture throughout the cluster with a thin
argon coating.
