N2 Reactivity of Positive Tungsten Cluster Ions

  • 摘要: 用激光蒸发团簇源产生Wn团簇束 ,团簇通过一个充有N2 气体分子的低压反应池 ,利用飞行时间质谱探测反应产物 ,在单次碰撞条件下研究了W+ 10 —W+ 50 和N2 分子的反应性 ,在室温条件下测量了N2 分子与W+ n 团簇反应的反应几率 .n =10— 2 6的团簇与N2 分子的反应几率与团簇尺寸有很强的相关性 ,n =16 ,2 2 ,2 3的团簇有较高的反应性 .W+ n 与N2 分子的反应性与Wn与N2 分子的反应性显示出相似的规律性. A beam of tungsten clusters, seeded in He gas, is produced in a pulsed laser vaporization source. We have studied the size-dependent reactivity of positive tungsten cluster ions with N 2 under single-collision conditions by using laser-vaporization source, low-pressure reaction cell and time-of-flight mass spectrometer. The reaction probability with N 2 molecule was measured as a function of cluster size, W + 10-W + 50, for clusters produced at room temperature...
