THE SOFT X-RAY SPECTRA OF LITHIUM, MAGNESIUM AND ALUMINIUM AND THEIR ALLOYS
The Li K and Mg L/sup 23/ spectra were observed from a range of Li--Mg alloys, evidence for electron transfer from magnesium being obtained. More distinct changes were observed for the same spectra when lithium was evaporated onto solid magnesium and magnesium onto solid lithium. Changes in the Li K and Al L/sup 23/ were observed when lithium was evaporated onto aluminum and in the Al Li/sub 2/ when aluminum was evapcrated onto magnesium. No changes greater than 5 x 10/sup -2/ ev were observed in edge wavelengths or edge widths although marked depopulation of higher energy states occurred in magnesium and aluminum. It is inferred that changes in the screening of K and L levels compensate almost exactly for the effects of electron transfer. The results of Catterall and Trotter were confirmed in that the magnesium band contracted and the lithium band extended on the low-energy side. Lithium deposited on aluminum shows a K spectrum without any metal edge, suggesting that the first zone is filled and that there is no overlap with the second zone. (auth)
