## Description

- description: "The unoccupied electronic states of Al-Pd-Ru quasicrystal (QC) have
    been investigated by X-ray absorption spectroscopy (XAS). In addition, the core-level
    peak binding energies have been verified by hard X-ray photoemission spectroscopy.
    From the comparison of the XAS spectra of the Al-Pd-Ru QC with those of single-element
    metals, the shift of the Al K edge can be explained by a shift in the Al 1s core
    level. In\r\ncontrast, the shifts of the Pd and Ru L3 edges cannot be explained
    solely by the shifts of the core levels. These differences are due to differences
    in the orbital-dependent partial density of states near the Fermi level."
