抄録	We have investigated the electronic structures of Ce-based 1/1 quasicrystal approximants Au₅₉.₂Ga₂₅.₇Ce₁₅.₁ and Au₆₀.₃Ga₂₆.₁Ce₁₃.₆ by hard X-ray photoemission (HAXPES) and high-resolution photoemission spectroscopy. The localized Ce 4f electronic states are revealed for both Au–Ga–Ce approximants. Moreover, disorders in the compounds notably affect their electronic states, which has been detected by the core-level HAXPES. Valence-band photoemission spectra show the slight spectral difference depending on the composition ratio, which can be explained by a rigid-band-like shift.
