摘要：

We have scattered protons and hydrogen atoms with energies of some keV from a LiF(001) surface under a grazing angle of incidence. From the intensity of Lyman-cr radiation (transition from n = 2 to n = 1, lambda = 121.6 nm) as a function of projectile energy for different azimuthal orientations of the crystal surface, we find clear evidence for a resonant coherent excitation of n = 2 states of hydrogen atoms in the oscillating electric field in front of the insulator surface.
