摘要：

A new experiment for measuring the reactivity of neutral metal clusters is presented. A low pressure reaction cell is used to measure the sticking of O2 and D2 gas on small transition metal clusters of Cu, Fe, Co and Ni. The experiment yields absolute values for the sticking, at a controlled number of cluster/gas collisions, facilitating comparison with theoretical calculations and other experiments. The most striking result of these preliminary measurements is the difference between oxygen sticking on Co(N) and on Cu(N), with the sticking on Cu(N) showing a clear correlation to the electronic shell model, while the sticking on Co(N) only exhibits a sharp increase with size, reaching sticking probability=1.0 for N > 25.
