A PRACTICAL METHOD FOR THE ANALYSIS OF OVERLAPPED PEAKS IN ENERGY-DISPERSIVE X-RAY-SPECTRA

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