The influence of disorder on the critical electron states in a quasiperiodic lattice is subject intense research. In this work, we report occurrence Anderson localization an icosahedral (i) polygrain quasicrystal Al-Pd-Re due to site using hard x-ray photoemission spectroscopy, resistivity, and density functional theory (DFT). Photoemission spectroscopy shows that enhanced at Fermi level $i$-Al...
