lectron energy-loss spectroscopy (EELS) has been used for studying the surface plasmon excitations in supported metal particles. Systematic theoretical and experimental investigations have been carried out on a postulated half-embedded particle model in specimen of Al/;A technique, REELS, in which EELS has been used in conjunction with reflection electron microscopy (REM) for studying the chemical compositions, atomic coordinations and electronic properties in surface layers of crystals has been developed.
