Using scattering-vector (q)-dependent electron-energy-loss spectroscopy (EELS), we found anisotropy of Liexcitation for. To achieve this, EELS spectra for(i.e., LiKedge overlapped withedge) were compared with those ofedge forunder dipole transition conditions. Then, first-principles calculations of loss functions and the Bethe-Salpeter equation of LiKedge were applied for. We also demonstrate that crystallographic orientation-dependent EELS forreflects the anisotropy of Liexcitation.
