Fjg. Deabajo et al., RESONANT COHERENT EXCITATION TO THE CONTINUUM IN GRAZING ION SURFACE COLLISIONS, Journal of physics. Condensed matter, 5, 1993, pp. 267-268
An extension of the Okorokov effect to the case in which the ion moves
near an oriented surface and the electron is ejected into the continu
um is considered. The effect of the screening of the initial electroni
c bound state on the final electron energy is analysed.
