Abstract A new experiment for measuring the reactivity of neutral metal clusters is presented. A low pressure reaction cell is used to measure the sticking ofO 2 andD 2 gas on small transition metal clusters ofCu, Fe, Co andNi. 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 onCo N and onCu N , with the sticking onCu N showing a clear correlation to the electronic shell model, while the sticking onCo N only exhibits a sharp increase with size, reaching sticking probability=1.0 forN〉25.
