Ad-a022 428 Symmetric Charge Transfer in Low-energy Ion-atom Collisions

Previous calculationn of ion-atom interactions by the pseudopotential and asymptotic methods are used in the computation of the cross section for Symmetrie charge transfer at energies below 1 keV. Ihe results for Li , Na , K*, Kb , CB and Ca ions are compared with data obtained in beam experiments, and by optical pumping techniques. The difference in the cross cections for TP-yg and P^/2 ions o...

Charge transfer and fragmentation in cluster–atom collisions

Charge transfer and fragmentation in collisions of sodium cluster ions with caesium atoms have been investigated theoretically within a microscopic framework called Non-adiabatic Quantum Molecular Dynamics. To illustrate the complexity of non-adiabatic cluster collisions, in particular the interplay between charge transfer and fragmentation, Na4 (2.7 keV) + Cs collisions are studied in detail w...

Tuning Charge Transfer in Ion-Surface Collisions at Hyperthermal Energies.

Charge exchange in ion-surface collisions may be influenced by surface adsorbates to alter the charge state of the scattered projectiles. We show here that the positive-ion yield, observed during ion scattering on metal surfaces at low incident energies, is greatly enhanced by adsorbing electronegative species onto the surface. Specifically, when beams of N(+) and O(+) ions are scattered off of...
