Production and ion-ion cooling of highly charged ions in electron string ion source
Review of Scientific Instruments, 2009The scheme of an internal injection of Au atoms into the working space of the “Krion-2” electron string ion source (ESIS) was applied and tested. In this scheme Au atoms are evaporated from the thin tungsten wire surface in vicinity of the source electron string. Ion beams with charge states up to Au51+ were produced.

If a potential electrolyte is added to an aqueous solution, it is conceivable that its dissociation may be so low that few ions are produced. It is also possible to make a solution from a true electrolyte so dilute that the number of ions in solution is very small. In both of these cases, the analysis completed in the previous chapter would be adequate

Positive Ion Transmission Mode Ion/Ion Reactions in a Hybrid Linear Ion Trap
Analytical Chemistry, 2004A triple quadrupole mass spectrometer capable of ion trapping experiments has been adapted for ion/ion reaction studies. The instrument is based on a commercially available linear ion trap (LIT) tandem mass spectrometer (i.e., an MDS SCIEX 2000 Q TRAP) that has been modified by mounting an atmospheric sampling glow discharge ionization (ASGDI) source ...

Effect of Light Ions on Ion-Ion Instability
AIP Conference Proceedings, 2003Effects of light ions on an ion‐ion instability are investigated in laboratory experiments. Spatial growth rates of the instability are measured by an interferometer method. The results show that the growth rate of the instability is affected by light ions and is reduced by increasing their amount.

Let us start by asking three questions. What types of ion-ion reaction have been studied? Why are these studies worthwhile? Where can more detailed information be found?

Theoretical and experimental data on ion-ion collisions are quite limited because this problem is a relatively young field of physics stimulated by recent research on thermonuclear fusion with inertial and magnetic confinement. Only since 1977, the experimental data on charge-exchange and ionization, involving singly or doubly charged ions, obtained by

The three-body recombination rate for molecular ions is calculated at low density, including the effect of dissociative collisions on the molecular complex initially formed by the recombination process. The effect of an increase in ionic mass due to the attachment of neutral molecules to the ion is also determined. The recombination rate is found to be

Ion Pumps, Ion Pathways, Ion Sites
1986There has been a rapidly growing list of ATP-fueled ion pumps. Most of these are H+-transporting ATPases ranging from the mitochondrial F1F0 ATPase through the H+ pump of intracellular organelles to the gastric H+-K+ ATPase (Racker, 1976; Cidon and Nelson, 1983; Sachs et al, 1976).

Electron-Ion and Ion Ion Recombination Processes
1994Publisher Summary This chapter discusses electron–ion and ion–ion recombination processes. Recombination processes have historically been distinguished by the mechanism responsible for disposal of the excess energy of recombination via radiative decay, dissociation or collision with third bodies. When intermediate resonant states become involved, the

Electron-Ion and Ion-Ion Collisions in Astrophysics
1986There has long been a close association between astrophysical studies and the development of atomic collision theory. This interaction took a major step forward when, some forty years ago, the real nature of the solar corona was first understood as a very hot tenuous plasma.
