Charge Transfer by H+ Ion Impact from H and Na Atoms Adsorbed on Al(100) Surface

Collision processes between the hydrogen ion H+ and an atom adsorbed on the Al(100) surface at grazing incident angles are investigated. A semiclassical close-coupling scheme is employed in order to calculate the probabilities for elastic scattering and charge transfer between the H+ ion and the hydrogenor sodium-atom adsorbed Al(100) surface for incident kinetic energies between 10 eV and 10 keV. Charge transfer is found to take place significantly between the H+ ion and the hydrogen atom, while it is suppressed in the case of the sodium atom. We also study the orientation and alignment of the cloud of the electron captured in 2p states by the H+ ion. Hitotsubashi Journal of Arts and Sciences 52 (2011), pp.23-42.
