英文摘要: The formation and photodissociation of Pb/S cluster ions, produced by two different ways of laser ablation, were studied with a tandem time-of-flight mass spectrometer. By laser direct ablation on a mixed Pb+S sample, the cluster ions with the compositions of PbnSn-1+ or PbnSn- were the most abundant species and can be identified as the stable components of Pb/S cluster ions. By laser double ablation on separated Pb sample and S sample, the products were PbnSm+(n=1-3, m=0-9) and PbnSm- (n=1-7, m=0-9) formed through reactions between Pb clusters and S clusters. From the distributions of cluster compositions and the photodissociation of clusters, we can confirm two different formation mechanisms of Pb/S clusters according to the producing ways of clusters.
