本文研究了13.1 keV轫致辐射对元素Ta、W、Au和Pb的强度比I(l α1,2)/I（l β1,2）、I(l α1,2)/I（Lγ）和I(l β1,2)/I（Lγ）。在这项工作中，实验值与理论结果和其他实验结果进行了比较。强度比的理论结果是用理论亚壳层光电离截面、分数x射线发射率、荧光产率和Coster-Kronig跃迁概率来计算的。实验值与理论结果吻合良好。与L1和L2亚壳层相比，随着激发能从59.5 keV增加到13.1 keV， L3亚壳层的电离截面Ta和W有了较大的增加。
We have studied the intensity ratios I(Lα1,2)/I(Lβ1,2), I(Lα1,2)/I(Lγ) and I(Lβ1,2)/I(Lγ) for elements Ta, W, Au and Pb by 13.1 keV bremsstrahlung radiation. In this work, experimental values were compared with the theoretical results and other experimental results. Theoretical results of the intensity ratios were cal- culated with theoretical subshell photoionization cross sections, fractional X-ray emission rates, fluor- escence yields, and Coster–Kronig transition probabilities. Good agreement can be observed between experimental values and theoretical results. Comparing with L1 and L2 subshells, the ionization cross section of L3 subshell shows a large increase for Ta and W with the variation of excitation energy from 59.5 keV to 13.1 keV.
