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 241Am 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.
