The detection of effective atomic numbers of some potassium compounds using direct and linear differential scattering methods

Abstract

In this work, the direct method and the linear differential scattering method were used to detect the experimental effective atomic numbers of some potassium compounds ( $$\hbox {KH}_{2}\hbox {PO}_{4}$$ , $$\hbox {KNO}_{3}$$ , $$\hbox {K}_{2}\hbox {S}_{2}\hbox {O}_{8}$$ , KOH, $$\hbox {K}_{2}\hbox {HPO}_{4}$$ , $$\hbox {K}_{2}\hbox {SO}_{4}$$ , KCl, $$\hbox {KIO}_{3}$$ and KI). The experiment has been done by using $$^{241}\hbox {Am}$$ radioactive source, a Si(Li) detector and an energy-dispersive X-ray fluorescence spectrometer (EDXRFS). The experimental effective atomic numbers were compared with the effective atomic numbers obtained using WinXCom, FFAST, non-relativistic theory (NRT) and relativistic theory (RT).
