The experimental results were compared with theoretically predicted values based on relativistic Hartree-Slater and Hartree-Fock theories, a comparison that was found to be in good agreement to within the experimental uncertainties.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:X-ray production cross sections of $K\alpha_1$, $K\alpha_2$, $K\beta'_1$ (= $K\beta{\cal B}_1$ + $K\beta_3$ + $K\beta_5$) and $K\beta'_2$ (= $K\beta_2$ + $K\beta_4$ + transitions from higher levels) lines have been measured and theoretically calculated for six elements with 62 $\leq Z \leq$74 at excitation energy of 78.706 keV, the weighted avarage of K conversion x-rays emitted from Bi.
