Ion-Ion Collisions Basic research . And in todays world everything is dynamic. The probabilities of these processes depend on many parameters like for example relative velocity of the collision partners and distance of closest approach.
Approximations are usually neccessary in the theoretical treatment of such dynamic processes.
One often used approximation for example is the treatment of the electrons as independent particles in the collision. While many experiments investigate the dynamics of collisions between ions and neutral atoms or molecules, we go one step further and study the same processes in collisions between two ions. This has the great advantage, that we are able to tailor the collision system to the theoretical approximations. In collisions between ions we can for example look at charge transfer reactions in a whole series of light, homonuclear collision systems and still assert, that both collision partners together have only one electron. But ion-ion collisions also play an important role in the world around us.
