Zusammenfassung

Photoelectron spectra of mass-separated Nbn- clusters reveal an even/odd alternation for n56 17, indicating a closed electronic shell of the neutral even-numbered clusters. The HOMO LUMO gap of Nb8, Nb10, and Nb16 is found to be larger than that of the other even-numbered clusters, which correlates with the low H2 reactivities of these species. The spectrum of Nb15- is different from all other clusters in this size range, which might be an indication for a geometric shell closing. The influence of the electronic structure of the clusters on the reactivity is discussed.
