Electron-Ion, Ion-Ion, and Ion-Neutral Interactions

1990
In my talk, I will present an overview of ongoing work in the area of electron-ion, ion-ion, and ion-neutral reactions. Clearly, this is a very wide field. Rather than trying to cover the whole field, I will focus my discussion on effects which are of importance in high-pressure plasmas, where the “high pressure” regime is defined as that in which ...

Electron–Ion and Ion–Ion Dissociative Recombination of Oxygen. II. Ion–Ion Recombination

The Journal of Chemical Physics, 1968
The 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 Interactions

2001
Describe and give examples of ionophore, ionogen, strong and waek electrolyte. Why is the charge density around a reference ion not zero when the whole solution is electroneutral? Explain succinctly the Debye-Huckel approach to their ionic-cloud theory.

Ion-ion recombination at high ion density

Journal of Physics B: Atomic and Molecular Physics, 1985
By 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 Interactions

1973
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.

Ion–Ion Collisions Involving Fullerene Ions

Fullerenes, Nanotubes and Carbon Nanostructures, 2005
Abstract Fullerenes are a direct link between atoms with discrete electronic energy levels and solids with a band structure and a well defined surface. In collision experiments, both between energetic ions or electrons and neutral C60 molecules [Walch, B.; Cocke, C.L.; Voelpel, R.; Salzborn, E.

Ion-ion recombination in an ambient ion gas

Journal of Physics B: Atomic and Molecular Physics, 1982
Attention is drawn to collisional ion-ion recombination X++Y-+X+ (or Y-) to XY+X+ (or Y-) which can be important when the ion density ni is very high. If, for example, X+ is Kr+ and Y- is F- the recombination coefficient alpha i is 3.0*10-7 (300/ theta )4.5(ni/1015) cm3 s-1 where theta is the temperature.

Ion-Ion Collisions and Ion Storage Rings

Physica Scripta, 1988
Improved 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.

Ion-Ion Neutralization.

1982
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 ...

Ion-ion collisions involving H− ions

AIP Conference Proceedings, 1990
A report is given on recent crossed‐beams experiments studying single‐ and double‐electron removal from H− in energetic collisions with Arq+ (q≤8) ions. The data is discussed with respect to conversion efficiencies of H− to neutral H0 in plasma neutralizers proposed for efficient neutral beam heating of future fusion devices.
