Ion-ion recombination at high ion density
Journal of Physics B: Atomic and Molecular Physics, 1985By appeal to a Thomson-style treatment of recombination, it is shown that the rate for recombination of ions generated with uniform frequency within a reaction volume is a factor of 9/4 times greater than the rate for recombination of ions which approach each other from infinite separation.

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.

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).

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?

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 ...

Ion-ion collisions belong to the fundamental processes in all types of plasmas in astrophysical objects (e.g. the earth’s ionoshpere or the solar corona) as well as in laboratory discharges (for example in thermonuclear fusion). The knowledge of cross sections for ion-ion collision processes is therefore essential for the modeling of these plasmas.

Cross section of ion excitation in ion-ion collision
Physics Letters A, 1979Abstract The “effective Feynman diagram” technique introduced in a previous paper is used to express the cross section of ion excitation in ion-ion collisions (A + B → A ∗ + B) in terms of the corresponding photon resonance absorption (hv + A → A ∗ ) and Thomson-scattering ( hv + B → hv + B ) cross sections.

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
