A model has been given for the breaking-up of an ionic crystal into free ions which stabilize themselves in solution with solvent sheaths. One central theme guided the account, the interaction of an ion with its neighboring water molecule.

Abstract : A variable-temperature FALP/SIFT apparatus has been built which combines the essential features of the versatile Flowing Afterglow/Langmuir Probe (FALP) and Selected Ion Flow Tube (SIFT) apparatuses. It has been used to determine the coefficients for the recombination reactions of NO+ and 02+ ions with electrons over the temperature range ...

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

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 ...

The Journal of Chemical Physics, 1964
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

Electron–Ion and Ion–Ion Dissociative Recombination of Oxygen. II. Ion–Ion Recombination
The Journal of Chemical Physics, 1968The rate coefficient and the thermal cross section for the oxygen ion–ion dissociative recombination are calculated using the semiclassical formalism. The motion of the heavy particles (positive and negative ions) in their mutual Coulomb field is treated classically. At certain ranges of the ion–ion separation (determined from energy conservation), the

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.

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.

Ion-Ion Collisions and Ion Storage Rings
Physica Scripta, 1988Improved understanding of fundamental ion-ion interactions is expected to emerge from research carried out with ion storage rings. In this short survey the significant advantages and unique features that make stored ions useful targets for collision experiments are reviewed and discussed.
