Measurement of photon-induced K x-rays production cross sections for elements with 62 $leq Z leq$74

Abstract

X-ray production cross sections of $Kalpha_1$, $Kalpha_2$, $Kbeta'_1$ (= $Kbeta{cal B}_1$ + $Kbeta_3$ + $Kbeta_5$) and $Kbeta'_2$ (= $Kbeta_2$ + $Kbeta_4$ + 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. 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.
