Abstract
A simplified version of a semiclassical common eikonal formalism for the description of resonant charge transfer occurring in atom–surface scattering has been extended to incorporate the effect of motion of the surface atom on the charge-transfer probability. Specifically, the dependence of the ionization probability on the initial kinetic energy is derived explicitly. The formalism is applied to the scattering of hyperthermal sodium atoms from the W(110) surface. The results show that the ionization probabilities display Stückelberg oscillations as a function of initial kinetic energy. The effect of motion of the surface atom can be seen in the appreciable change in the magnitude and frequency of these oscillations of the ionization probabilities. The results also give an indication of the importance of energy transfer in determining the ionization probability of hyperthermal sodium atoms on the W(110) surface.
