Abstract: | Using the gasaggregation technique it is possible to generate metal clusters in narrow size distributions and to vary their mean size by adjusting the cell parameters. The high intensity of this source allows to detect besides singly charged clusters also multiply charged ones. Ag n 2+ and Ag n 3+ are observed forn≧9 andn≧31, respectively; i.e. at values well below the critical sizes reported for spheres. |
