摘要：

Electron emission from H-0 projectiles (1-20 keV) grazingly scattered off a LiF(001) single-crystal surface has been studied for impact angles from 0.5 degrees to 1.8 degrees. We observe that the threshold energy for electron emission increases with smaller projectile impact angle, whereas at higher impact energies smaller angles are more efficient for producing electrons. Our data are analyzed in terms of position- and velocity-dependent electron production rates that indicate that an electron promotion mechanism is responsible for electron emission.
