    Notizen: Abstract The velocity distribution of sodium chloride clusters produced by inert gas condensation is determined by means of a mechanical chopping technique. It is found to be the same for all cluster sizes between 1 and more than 200 molecular units per cluster, ruling out the possibility of cluster mass separation by velocity filters. This is explained by an adiabatic expansion occuring during the cluster's exit from the condensation chamber into the high vacuum of the mass spectrometer.

    Alkali-hydride water cluster ions (1993)

    Notizen: Abstract Using a CO2 laser we have desorbed LiOH and NaOH from a solid target into an expanding inert gas jet pulse. Subsequently the beam was ionized by photons from a UV laser. Surprisingly, we observed in mass spectra metal water clusters and metal-hydride water clusters. For the metals M=Li, Na we find that the [M(H2O)n]+ peaks are dominant for small clusters, while for large clusters (n〉20) the [MH(H2O)n]+ peaks are dominant. This indicates that the clathrate (H2O)20 may play an important role in the formation of metallo-water clusters.

    Delayed ionization of IR-laser excited C60 (1993)

    Notizen: Abstract Using a pulsed CO2 laser we have desorbed C60 clusters from a solid target into an expanding He jet, coupled to a time-of-flight mass spectrometer. We observed self ionization of the excited clusters with a time delay of 120 ±20 µs. This is large compared to previously reported delays of up to 15 µs after laser excitation with visible or ultraviolet light. We suggest that the delayed ionization is caused by structural isomers of hot C60 clusters differing from the truncated-icosahedron structure.
