Grazing incidence fast atom diffraction has mainly been investigated with helium atoms, considered as the best possible choice for surface analysis. This article presents experimental profiles recorded neon projectile, between 300 eV and 4 keV kinetic energy angles θi 0.3 1.5° along three different directions of a LiF(001) crystal surface. These correspond to perpendicular ranging from few meV up almost 1 eV. A careful analysis scattering profile allows us extract diffracted intensities even when inelastic effects become so large that most quantum signatures have disappeared. The relevance this approach is discussed in terms topology.
