چکیده انگلیسی
Angular distributions for scattering of 12Â keV He atoms from a LiF(0Â 0Â 1) surface under a grazing angle of incidence were recorded in coincidence with the projectile energy loss and the number of electrons emitted from the target surface during the collision. For scattering along the low indexed ã1Â 1Â 0ã and ã1Â 0Â 0ã directions of the crystal surface collisional rainbow peaks were observed. For scattering along a ã1Â 1Â 0ã direction the resulting rainbow peaks can be attributed to scattering from strings of anions which form active sites for charge exchange and emission of electrons. The data can be interpreted by trajectory computer simulations where charge transfer takes place from Fâ sites.
