Spectroscopy of Na3,quantization of the vibronic pseudorotation which constitutes the first direct verification of the adiabatic sign-change theorem. Photofragmentation is studied by depletion spectroscopy and the 420 nm system is found to be completely predissociated. The structure of the ground state and the ionizati

Electronic Structure and Bonding in Clusters: Theoretical Studies,r ground states have always multiplicity higher than the lowest possible value. However, the energy difference between ground and lowest low spin state decreases with increasing cluster size. The energy range of the Al. cluster valence levels is comparable with the width of the occupied part of the

Experiments on Size-Selected Metal Cluster Ions in a Triple Quadrupole Arrangement,esulting mono- dispersed cluster ion beam was introduced into a quadrupole drift tube, where it interacted with a laser beam or reacted with an introduced gas. All inelastic scattering events were recorded with a subsequent quadrupole mass filter. The results exhibited a high sensitivity of positive

Sputtered Metal Cluster Ions: Unimolecular Decomposition and Collision Induced Fragmentation,., W., and Pb. is investigated under UHV conditions. The time evolution of the decay allows a glimpse into the cluster formation/fragmentation process. Highly excited metal cluster ions decompose mainly by evaporating single neutral atoms with rates reaching 100%. The collision induced fragmentation

The Chemistry and Physics of Molecular Surfaces, properties of clusters of both transition metals and other refractory elements containing from one to several hundred atoms. The gas-phase reactivity of clusters towards a variety of reagents is explored using a fast-flow reactor system. Strong cluster size-dependent variations in reactivity are ob

Analysis of the Reactivity of Small Cobalt Clusters,tions were done for simple geometries with the optimized number of interatomic bonds, and both for the bond length of the cobalt dimer and the bulk metal. The Fermi energy is found to be smaller for Co. clusters with .= 3, 4, 5 and .>10 than for the other ones. The variation of the Fermi energy with
