Outline of Final Research Achievements	Recent progress of the transmission electron microscopy has been allowed us to obtain the high-resolution electron energy-loss spectra (EELS). These spectra include exciton transition from core electrons which was not available through conventional EELS measurements. The present study develops novel theoretical methods that apply both of core-electron vs. exciton and exciton vs. phonon interactions based on Bethe-Salpeter equation.
