We find that the charge-transfer dynamics at the reconstructed surface is dependent on both the surface-electronic structure and orientation of the projectile trajectory relative to the crystal azimuthal directions. Our results are in good quantitative agreement with the measured Hˉ fractions of Maazouz and Esaulov [Surf. Sci. 398 49 (1998)] for scattering trajectories that are aligned perpendicularly to rows of silicon dimers.en-USThis Item is protected by copyright and/or related rights.
