Abstract:
In this study, full widths at half maximum (FWHM), asymmetry indexes, chemical shifts (ΔE) and Kβ-to-Kα X-ray intensity ratios of some pure metals (Mn, Fe, Cu and Zn) and some of their oxidized compounds (Mn2O3, Fe2O3, Fe3O4, Cu2O3 and ZnO) were investigated. The samples were excited by 59.54 keV photons emitted from a241Am radioisotopes source and characteristic K X-rays emitted from the samples were counted by a Si(Li) detector. The results have shown that the Kβ-to-Kα X-ray intensity ratios, asymmetry indexes, chemical shifts and full widths at half maximum (FWHM) values can change with sample sizes.
