Abstract

X-ray production cross sections of Ka1, Ka2, Kb'1 (= Kb {\ss}1 + Kb3 + Kb5) and Kb'2 (= Kb2 + Kb4 + transitions from higher levels) lines have been measured and theoretically calculated for six elements with 62 \le Z \le 74 at excitation energy of 78.706 keV, the weighted avarage of K conversion x-rays emitted from Bi. 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.
