The observation of what are believed to be small multiply charged clusters generated in a laser-produced plasma is reported and discussed, and a possible formation mechanism is proposed. Homonuclear gold cluster ions comprising three atoms and carrying charges of up to + 5, and of four atoms carryin

β¦ Synopsis
The results of collision-induced fragmentation measurements on Au:+, Au:*, Au:+, and Au:+ are presented. In all cases, channels involving fission (separation of charged fragments) are observed. Neutral loss channels are not observed. Fission crosssections (of the order of 50-100 A' with Xe) are much larger than fragmentation cross-sections of singly charged ions and are relatively insensitive to the target gas. The collision-energy dependence of the branching ratios shows that Au:++Au:+ +A$ and Au:+~Au:+ + Au+ are the respective lowest decay channels.

Small, highly charged sodium clusters have been produced by multi-step ionization of large clusters followed by evaporative shrinking. The critical size, nc, beyond which Na~ + are stable obeys the approximate relation he= 8z 2. However, significant deviations from constant z2/nΒ’ are dearly evident.
Small doubly charged niobium clusters are observed in a molecular beam emerging from a laser vaporization/supersonic expansion source if electron impact ionization is utilized in the expansion region. Doubly charged clusters from n=2 to n= I5 are readily detected. The doubly charged dimer cation has
Singly charged vanadium cluster ions from an external laser-vaporization source are accumulated in a Penning trap. They are subjected to electron bombardment which leads to further ionization. The charge states produced are analyzed by time-of-flight mass spectrometry after axial ejection from the t
