Aluminum L/sub 2,3/ soft-x-ray emission spectra have been observed for several aluminum-manganese alloys exhibiting icosahedral, decagonal, and the normal crystalline symmetries. The spectra of all the alloys are qualitatively similar and are slightly narrower (approx.0.2 eV) than the width observed for metallic aluminum. Compared to the sample with crystalline symmetry, the quasicrystals show no chemical shift and a decrease in the partial density of states of s and d symmetry at the Fermi energy, contradicting the predictions of several calculations
