Extraction and Acceleration of Ions from an Ion-Ion Plasma
AIP Conference Proceedings, 2011Extraction and acceleration of positive and negative ions from a strong electronegative plasma and from an ion‐ion plasma is investigated in the PEGASES thruster, working with SF6. The plasma is generated in a cylindrical quartz tube terminated by metallic endplates.

Electron-Ion, Ion-Ion, and Ion-Neutral Interactions
1990In 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, 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 Collisions Involving Fullerene Ions
Fullerenes, Nanotubes and Carbon Nanostructures, 2005Abstract 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 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.

Ion-ion recombination in an ambient ion gas
Journal of Physics B: Atomic and Molecular Physics, 1982Attention 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 involving H− ions
AIP Conference Proceedings, 1990A 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.

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.

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.

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.
