The K emission band of Li and L/sub 23/ emission bands of Mg and Al have been measured for Li--Mg and Li--Al prepared in a range of concentrations either by coevaporation or by evaporating thin films of Li on Mg(Al) substrates or Mg(Al) on Li substrates. The Li K spectrum is nearly unchanged at all alloy concentrations in the Li--Mg system but broadens and develops a low energy shoulder for large Al concentrations in the Li--Al system. Both Mg and Al L/sub 23/ spectra are narrower and more peaked at low energy in the equilibrium alloys than in the pure metals. The many-body threshold peaks on the Al and Mg L/sub 23/ spectra are generally suppressed by alloying with Li, except for low temperature coevaporated Li--Al samples where the peak persists to very Li-rich alloys. Data for a Li/sub 80/Mg/sub 20/ alloy are compared with KKR-CPA calculations, and good agreement is found for both the Li K spectrum and the Mg L spectrum.
