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 muc

It is proposed that multiply charged water clusters contain varying combinations of the ion pairs H+ (probably as H30+ ) and OH+ (probably as HaO: ) acting as charge carriers. Formation of H+ and OH+ is discussed in terms of single-or double-ioniza-.\_ tion events on either individual or pairs of wa
## Abstract Tandem mass spectra of a variety of adenineβcontaining deoxynucleic acid anions obtained using collisional activation in a quadrupole ion trap are described. Data are reported for singly charged monoβ, diβ and trinucleotide species, and also for multiply charged anions derived from triβ
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
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
