Abstract
For the first transition-series metals with filled or partly filled 3d shells, the final states of the soft L x-ray emission bands are valence hole states ant their L emission spectra have been intensively used to investigate the valence electronic structure. The possible use of the Lα lines of these elements for quantitative analysis by x-ray spectrometry with the Electron Probe Micro-Analyzer is discussed and illustrated for the case of the Zn Lα emission band analyzed with a TAP monochromator.As shown in Figure 1 the Zn Lα emission band of pure metallic zinc exhibits an asymmetrical shape resulting from a broad tail occurring on the short wavelength side (high energy side) of the peak. This tail is the envelope of many unresolved closely spaced satellite features which arise from the deexcitation of the L3 vacancy in the presence of multiple outer vacancies. The digitally recorded Zn Lα emission band was processed by adding Gaussian offsets to the pseudo-Voigt profile of the Zn Lα diagram line used as a fitting function.
