Abstract

Specific features of the excitation of the X-ray fluorescence of fluorine in the presence of petrogenic elements are studied experimentally. The dependence of the intensity of the FKα-line on the atomic number of macroelements entering the composition of rocks is studied. It is found that the major contribution to the intensity of the FKα-line due to the effect of selective excitation is made by sodium fluorescence. The dependence of the intensity of the FKα-line on elements with atomic numbers 11 < Z ≤ 26 exhibits a maximum in the region Z ≈ 20–22. This is due to the contribution of photo and Auger electrons of the listed elements. The obtained experimental data indicate that the yield of X-ray fluorescence of fluorine depends on the compound containing fluorine. The optimum operation mode of the X-ray tube was chosen for the determination of the FKα-line.

石油元素在激发X射线荧光中的作用

摘要

实验研究了在成矿元素存在下氟的X射线荧光激发的特定特征。研究了F Kα线的强度对进入岩石组成的宏观元素原子序数的依赖性。据发现，与F的强度的主要贡献ķ α线由于选择性的激励的作用是通过荧光钠制成。F Kα线的强度对原子序数11 < Z≤26的元素的依赖性在区域Z中最大≈20-22。这是由于所列元素的光电子和俄歇电子的贡献。获得的实验数据表明，氟的X射线荧光的产率取决于含氟的化合物。选择X射线管的最佳操作模式来确定F Kα线。
