Extract

In this article we present the experimental data on L3-absorption spectra of metallic tin. and tin in SnO2 . We have used (i) a bent crystal spectrometer and (ii) a high resolution flat crystal spectrometer with a microfocus target as the source for the continuum radiation. We have observed a “white line” on the low energy side of the primary L3-absorption edge of Sn in SnO2. Similar “white lines” in absorption spectra were reported earlier by M. Siegbahn in rare earth elements with f-vancies, who designated such lines appearing immedlately on the low energy side of the primary absorption edge as “white lines” in absorption spectra. It is interesting to note that metallic tin does not reveal the “white line”, while Sn in SnO2 clearly revealed a sharp white line on the low energy side of the primary absorption edge.
