摘要：

The mass spectra of alkali-halide cluster ions M(MX)n+ and X(MX)n-, produced by laser vaporization of a solid sample, were measured by tilted-plate time-of-flight mass spectrometry. The measured abundances of sodium chloride clusters (n=1200), sodium iodide clusters (n=1125), cesium chloride clusters (n=1125), and cesium iodide clusters (n=1100) confirm that surface terraces are the most stable additions to a cuboid base lattice. Also, the spectra show that the relative stabilities of certain cluster ions are dependent on the ionic radii of the constituent atoms. © 1990 The American Physical Society.
