Investigation on Li (i = l, β, and γ)–to-Lα X-ray Intensity Ratios of Tl in Thallium Compounds

Abstract

The Li (i = l, β, and γ)-to-Lα X-ray intensity ratios of Tl in some thallium compounds were measured by EDXRF spectrometer. These compounds were excited by 59.5 keV gamma-rays from a 241 Am annular radioactive source. L X-rays emitted by the compounds were counted using an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. Li-to-Lα X-ray intensity ratios of Tl in these compounds are compared with that of the pure Tl calculated theoretically. While the values of Ll/Lα and Lγ/Lα intensity ratios are compatible with the theoretically calculated value, the values of Lβ/Lα intensity ratios have differences.
