英文摘要	Time-of-flight mass spectrometry was used to study Mn-Se and Mn-O-Se cluster ions produced by laser direct vaporization of solid samples, In Mn-Se binary cluster ions, (MnSe)(n)(+) is the main composition of positive cluster ions, while [(MnSe)(n)Se](-) is the main composition of negative cluster ions. When a mass-selected (MnSe)(n)(+) was photolyzed, the photolysis produt ions have the same general composition (MnSe)(m)(+). In Mn-O-Se ternary system, the main positive cluster ions produced are Mn-O binary clusters, in which [(MnO)(n)](+) has a high intensity, while the negative cluster ions include Se-n(-), [SenO](-), [SenO(3)](-) and [MnSen](-). It seems that the cluster ions were produced by the vaporization of solid sample and this conforms to a gas-phase aggregation mechanism.
