Photoelectron spectra of a fivefold quasicrystalline alloy Al₇₀Pd₂₁Mn₉ and a related cubic alloy Al₆₀Pd₂₅Mn₁₅ reveal two noteworthy features. The first is that the Pd 3dlines fall at binding energies which are 2.2 eV higher than in pure Pd. A similar shift is observed for Pd in other alloys. The second noteworthy feature is that the Mn 2p_3/2 line is very sharp in the quasicrystal. Fitting the experimental peaks with a Doniach-Sunjic line shpae suggests that the position and density of Mn states near E_Fis very ...
