Kβ/Kα intensity ratios for rare earth compounds using radioisotope induced X-ray fluorescence
Abstract
Measurements of the Kβ to Kα intensity yield for the rare earth elements in various chemical compounds and as the pure elements have been made utilising radioisotope induced fluorescence and a hyperpure germanium (HpGe) detection system. Deviations from the ratios anticipated from theoretical considerations or from existing compilations have been found for LaB6, Ce(NH4)2(NO3)6, Pr6O11, Gd (citrate solution), Gd (EDTA solution), Tb4O7, Lu2O3, Lu (foil) and Eu in acid solution.
