A Practical Method for the Analysis of Overlapped Peaks in Energy Dispersive X-Ray Spectra

Abstract

ABSTRACT In this study a practical method for the spectral analysis of some overlapped characteristic X-ray peaks is presented. The overlapped characteristic K, and K, peaks and the artificially overlapped two K, peaks (peak doublet) of arsenic obtained by the radioisotope-excited, energy dispersive X-ray fluorescence (EDXRF) technique, are resolved. A total of 34 overlapped peak systems were investigated: the proposed method provided 18 reliable results, whereas the first and the second methods gave 15 and 1, respectively. The intensity ratios of Kβ/Kα, obtained by the novel method are also in good agreement with the theoretical relativistic Hartree-Slater values.
