摘要: We report the high-resolution electron Compton profiles of graphite along three main crystallographic directions [ 101¯0], 112¯0], and 0001] by recording energy-loss spectra at a large momentum transfer using transmission microscope. A significant anisotropy is observed. The experimental results are in good agreement with theoretical calculations that use full-potential linearized augmented plane wave method based on local-density approximation. Electron scattering from solids (ECOSS) shown to be sensitive probe binding structure material. ECOSS should considered as viable technique determine distribution nano-materials because its short time high resolution.
