The influence of the structure of atomic systems on the dynamics of electron exchange in ion-ion collision

One electron exchange between the Rydberg states of ions is elaborated within the time symmetrized framework of two-wave-function model. It was observed that in an atomic collision, the population of ionic states by electron exchange, is strongly conditioned by the structure of the subsystem itself, especially at intermediate velocities. This circumstance is particularly pronounced when determining the ion-ion distances at which the charge exchange is most likely. The specificity of the model is reflected in the fact that the determination of the electron capture distance is carried out at fixed initial and final states of the system under consideration. As an illustrative example, XeVIII was used as a target of collision process, i.e. ion Xe8+ initially populated in Rydberg state nu(B) = (n(B) = 8, l(B) = 0, m(B) = 0), while argon ions ArZA+ were used as projectiles in the core charge range Z(A) is an element of [3, 9].
