Sažetak
The Tandem accelerator facility of the Ruđer Bošković Institute is equipped with high resolution wavelength dispersive spectrometer system (WDS) used for chemical state analysis by PIXE method. In our recently performed analysis of vanadium and titanium samples, the most important conclusions are derived from relative intensities and energies of the Kβ 5 and Kβ '' X-ray lines extracted from fitted Kβ spectra [1]. In some cases results of analysis are very sensitive on the fitting procedures, especially on how they handle absorption K edge feature. In this work we report the influence of fit models on analysis of spectra and final interpretation of chemical states.
