Measurement of L X-ray production cross sections and relative intensities of some lanthanide compounds depending on the temperature

L X-ray intensity ratios for CeO2, Sm-2(SO4)(3), Ho2O3, and Yb2O3 compounds were experimentally investigated. The measurements were gauged following excitation by 59.54 keV gamma-rays from a 100 mCi Am-241 radioactive annular source at different temperatures in situ. Temperature change occurred between 50 degrees C and 400 degrees C. L X-ray emission spectra were obtained by using a solid-state Si(Li) X-ray detector. L X-ray production cross sections, intensity ratios, and full-width half maximum (FWHM) values for the compounds were determined by evaluating the emission spectra varying with the temperature. According to the results obtained, it was observed that L-beta 1 X-rays were less influenced in comparison with L alpha X-rays while L alpha X-rays were also less influenced in comparison with L beta(2) X-rays.
