英文摘要: The production mechanism of Cu/Cl binary clusters were investigated by laser vaporization of CuCl1 CuCl2, CuCl2 center dot 2H(2)O by time-of-flight mass spectrometry. We found that lager cluster size can be detected by using CuCl2 center dot 2H(2)O solid pellets than CuCl2 and CuCl. Only Cu+(CuCl)(n), (CuCl)(n)(+), n<8 were observed when 532 nm laser vaporized the Cucl. We also found almost the same cluster using CuCl2 and CuCl2 center dot 2H(2)O in the same mass range, deficit Cu clusters were dominated for clusters with more than five Cu atoms when using CuCl2, CuCl2 center dot 2H(2)O compounds. the relation of relative intensity I-n(2)/In-1In+2 vs, different size of clusters were almost the same using different compounds above. (CuCl)(3)(+)center dot(CuCl)(6)(+) ions in (CuCi)(n)(+) series, and Cu6Cl5+ in Cu(CuCl)(n)(+) series have special stability. The magic number observed above are different from those of alkali halide (MX) clusters, hexagonal structures were proposed for the above magic number clusters.
