Grazing incidence fast-atom diffraction (GIFAD) uses keV atoms to probe the topmost layer of crystalline surfaces. The are scattered by potential energy landscape surface onto elastic spots located at Bragg angles and on Laue circle. However, transfer a significant momentum surface, giving rise possible phonon excitation. This causes inelastic intensity spread above below circle along direction normal. relative contribution is well fitted Debye-Waller model adapted GIFAD, but composite...
