We report the application of the quantum approach, which takes full account of electron translation at low collisional energies, to the charge exchange process H, D + C4+ → H+, D+ + C3+(3s; 3p; 3d). The partial and the total integral cross sections of the process are calculated in the energy range from 1 till 60 eV/amu. It is shown that the present results are independent from the upper integration limit for numerical solution of the coupled channel equations although nonadiabatic couplings remain nonzero up to infinity. The calculated partial and total cross sections are in agreement with the previous low-energy calculations and the available experimental data. It is shown that for low collisional energies the isotopic effect takes place. The observed effect is explained in terms of the nonadiabatic dynamics. Full article

Processes involved in slow collisions between highly charged ions (HCI) and neutral targets are presented. First, the mechanisms responsible for double electron capture are discussed. We show that, while the electron-nucleus interaction is expected to be dominant at projectile velocities of about 0.5 a.u., the electron-electron interaction plays a decisive role during the collision and gains importance when the projectile velocity decreases. This interaction has also to be invoked in the capture of core electrons by HCI. Finally, the molecular fragmentation of H2 following the impact of HCI is studied. Full article

The alignment-dependent atomic model for treating electron transfer processes in ion-molecule collisions [Shingal and Lin, Phys. Rev. 1989, A40, 1302] is reviewed. This model has been applied to collisions between H+ and He2+ with H2, and recently also to collisions between He2+ and Ar2+ ions with H2+, where alignment effect is being explored experimentally.

The effect of the anisotropy of the interaction potential on ion-diatom non-adiabatic collisions is analized by considering the influence of the anisotropy on orientation averaged total cross sections for charge transfer in H++H2(X1Σ+g ) collisions. We discuss the possibility of employing simpli ed methods such as an isotropic approximation, where only the electronic energies and interactions of a single orientation are necessary. The use of several isotropic calculations to evaluate the orientation averaged cross section is analized. Full article

We have performed translational-spectroscopical measurements on single electron capture (SEC) by impact of slow (impact energy ≤ 1 keV) doubly charged ions on dinuclear molecules. For impact of C2+ and N2+ ions the influence of their metastable fractions on the SEC probability has been studied. For impact of 4He2+ on O2 and CO direct and dissociative SEC have been investigated. For all collision systems studied the principal SEC channels can be explained by the "reaction window" which results from multichannel-Landau-Zener treatments for the collisional quasimolecules.
