✦ Synopsis

Gas-phase metal clusters of antimony, bismuth, or antimony-bismuth alloys are prepared by laser vaporization and probed with UV laser photoionization in a time-of-flight mass spectrometer. Unusual size distributions are observed, ending at five-atom clusters. Fragmentation processes are extremely efficient at 193 nm for tetramer species regardless of elemental composition. There are striking similarities in cluster stability and fragmentation patterns in these systems.

Two reaction channels have been found when light hydrocarbon gases are introduced into the carrier gas of a plasma reactor coupled with a laser vaporization source employing a metal rod assembly. These involve dehydrogenation to produce pure carbon clusters, and formation of metal-carbon bonds to pr
