摘要：
Tellurium clusters in the size range of 2-20 atoms are produced by laser vaporization in a pulsed-nozzle molecular beam source. Cluster distributions are characterized by direct sampling of cations condensed from the vaporization plasma and by photoionization of neutral species. Mass-selected clusters are studied with ultraviolet laser photodissociation. Fragmentation preferentially produces the molecular species Te4, Te2+, Te5+, and Te7+. © 1990 American Chemical Society.
