摘要
Electronic and structural properties of the heavy fermion intermetallics CePd2Si2 and CeNi2Ge2 were determined using the techniques of low-energy electron diffraction, electron-energy-loss spectroscopy (EELS) and resonant photoemission. Atomically clean and well-ordered surfaces were prepared by evaporating the corresponding crystal onto a W(110) crystal. This preparation procedure allows the application of angle-resolved electron spectroscopic methods being sensitive to surface properties. The behavior of the rare-earth f states was determined by EELS. Resonant photoemission was carried out by tuneable synchrotron radiation allowing a direct assignment of the orbital nature of the electron states hybridizing in the valence band as well as to distinguish between states of the different constituents.
