Popis: Sharp negative lines have been observed in wavelength-dispersive (WD) spectra. These ‘holes’ can cause severe errors when analysing for trace elements near the lower levels of detection. The existence of the holes is explained in terms of diffraction from crystailographic planes other than those used in the WD analysis, and an overview is given of the theory necessary to predict the occurrence of the holes with emphasis on LiF(200) analysing crystals.
