英文摘要	The time-of-flight mass spectrometry was used to study Ag/Se cluster ions produced by laser ablation of solid samples, and a Laser Double Ablation Reactor was used to study the reaction of Ag and Se clusters. In Ag/Se binary cluster ions produced by laser ablation, [(Ag2Se)(n)Ag+], [(Ag2Se)(n)Ag-3(+)] are main compositions of positive cluster ions, while [(Ag2Se)(n)AgSe-], [(Ag2Se)(n)AgSe2-], [(Ag2Se)(n)Se-] are main compositions of negative cluster ions. The photolysis rates of positive cluster ions is higher than those of Ag/S clusters. During the laser double ablation experiment, the AgSen+ (n=4-9), AgSen- (n=4-7) were detected. In the series AgSe4+, the ions AgSe4+, AgSe6+ are comparatively abundant. It seems that the clustering mechanisms in the two processes are different.
