Abstract

Electronic structures of rare-earth hexaborides (RB₆)have been investigated by photoemission and inverse photoemissionspectroscopy. The X-ray photoemission (XPS) features of the 3d and 4dcore states of heavy R elements are interpreted in comparison with themultiplet calculation. The valence band spectra probed by XPS andX-ray bremsstrahlung isochromat spectroscopy (X-BIS) methods are fullyutilized to interpret the optical conductivity spectra.
