We have observed gas-phase reactions between N2 molecules and copper cluster cations, Cun+ (n = 2–17), formed by a modulated pulsed power magnetron sputtering cluster ion source. By introducing N2 gas effusively between the source and an acceleration region of a time-of-flight mass spectrometer in the vacuum chamber, N2-adsorbed copper cluster cations, CunN2+, were observed in mass spectra. The N2-adsorption reactivity of Cun+ was found to be relatively lower at n ≥ 10 than at the smaller n. The cluster-size dependence of N2-adsorption on Cun+ has a correlation with binding energies between Cun+ and N2 calculated by density functional theory.
