摘要：

The stability of a closed-shell metal cluster, Na-8, is studied in a variety of surroundings using ab initio molecular dynamics. On the insulating NaCl(001) surface, Na-8 is magic; even at 600 K it retains its intrinsic structure. On the Na(110) surface it spontaneously collapses, forming an epitaxial adlayer. In the vacuum, interaction with another Na-8 cluster destroys its shell structure and a deformed Na-16 is formed. The results are discussed in a context relevant to cluster-assembled structures.
