Abstract

The Li (i = l, α, β, and γ) production cross-sections, L-shell average fluorescence yields, and Coster-Kronig vacancy transfer factors for L3 subshell X-rays of thallium in some thallium compounds were determined using Energy Dispersive X-ray Fluorescence spectrometer. The compounds were excited by 59.5 keV gamma-rays from an Americium-241 annular radioactive source, and the L X-rays emitted by the compounds were counted using an ultra-low energy germanium detector with a resolution of 150 eV at 5.9 keV. The production cross-sections, average fluorescence yields, and Coster-Kronig vacancy transfer factors of thallium in these compounds were compared with theoretical calculations and available experimental values of the pure thallium.

摘要

大号 = αβ,和γ)生产的横截面,L壳平均荧光产率,和科斯特-克勒尼希空缺转移因子对于L 3使用能量色散 X 射线荧光光谱仪测定某些铊化合物中铊的亚壳层 X 射线。这些化合物被来自镅 241 环形放射源的 59.5 keV 伽马射线激发,并使用分辨率为 150 eV、5.9 keV 的超低能锗探测器对化合物发射的 L X 射线进行计数。将这些化合物中铊的生产截面、平均荧光产率和 Coster-Kronig 空位转移因子与纯铊的理论计算和可用实验值进行比较。
