Notizen: Experimental measurements of the relative intensity of the escape peak produced in an intrinsic Ge detector agree quite well with the calculated intensities based on a theoretical model. Contrary to the Si(Li) detector Kα as well as Kβ escape peaks are observed. In the energy region 11-25 keV the Ge Kα escape peak intensities vary from 16.3 to 4.7% and the Ge Kβ escape peak from 2.4 to 0.9% of that to the parent line. Therefore, the escape peaks are not negligible in X-ray fluorescence analysis, and it may be necessary to numerically correct for them or, by a suitable choice of excitation energy, avoid them completely.
