Determination of the effect of temperature on relative L X-ray intensity ratio of gadolinium, dysprosium and erbium

Abstract In this study, Lα/Lβ1 and Lα/Lβ2 X-ray intensity ratios for gadolinium, dysprosium and erbium elements were experimentally determined. L X-ray intensity ratio measurements were gauged at several temperatures (50, 100, 50, 150, 200, 250, 300, 350 and 400 °C) using an excitation energy of 59.54 keV γ-rays emitted from a 100 mCi 241Am radioactive source. L X-ray emission spectra were detected using a Si (Li) detector system with a resolution of 160 eV at 5.96 keV coupled with a computer-controlled multi-channel analyzer. L X-ray production cross-sections (σLα, σLβ1 and σLβ2) of the lanthanide elements were calculated by assessing the emission spectra. The variation with temperature of each parameter was given in graphical forms and tabulated. It was observed that the parameters were affected by temperature. According to these results, it is determined that the L X-ray intensity ratios and L X-ray production cross-sections of pure Gd, Dy and Er elements changed and were affected by temperature.
