    Abstract

    Measurements with photoemission spectroscopy in the photon-energy range 35-150 eV have been used to measure the valence band of the stable icosahedral Al70Pd20Fe10. The maxima of the Pd 4d- and Mn 3d-derived states are respectively at 3.6 and 0.7 eV below the Fermi level. The strong decrease of intensity towards the Fermi level suggests the presence of a pseudogap at the Fermi level. No unusual features in the valence band of icosahedral Al70Pd20Mn10, which could be ascribed to its quasiperiodic nature, are observed within the resolution of the experiment.
