Abstract
Threshold photoionization experiments on beams of rare gas atomic clusters doped with a single metal atom (AlArN; N = 1-200) reveal pronounced discontinuities in cluster abundances as a function of N. Abundances at the photoionization thresholds for clusters containing up to 60 atoms and fragmentation probabilities measured on a 50-μs time scale provide compelling evidence that the neutral clusters, as well as the corresponding ions, pack in icosahedral shells.
