我们展示了重离子诱导x射线产生截面的靶厚度依赖性如何用于将测量的K REC（辐射电子捕获）强度归一化为具有K空位的入射离子的比例。如果假设Cu中的所有M层和n层电子都参与了REC过程，则Cl离子在Cu靶上的REC实验截面与Bethe和Salpeter的自由电子理论很好地吻合。
We show how the target-thickness dependence of heavy-ion -induced x-ray production cross sections can be used to normalize the measured K REC (radiative electron capture) intensity to the fraction of incident ions with K vacancies. Experimental REC cross sections for Cl ions on Cu targets are in good agreement with the free-electron theory of Bethe and Salpeter if it is asumed that all of the M- and N-shell electron in Cu contribute to the REC process.
