Kα satellite energies in x-ray spectra

Abstract

The fine structure of KL-LL transitions in atoms with Z = 10 to 46 has been calculated in the intermediate coupling approximation using Slater formulae for two-hole interaction energies. Initial-state energies have been calculated using available experimental data for single-hole excited state energies and Hartree-Fock derived data for the Slater integrals F k and G k . These energies have been corrected for adiabatic relaxation of orbitals as well as for solid state effects. Final-state energies have been derived from the available KLL Auger transition energies. The calculated values for KL-LL transitions have been found to be in excellent agreement with those observed in Kα 3,4 spectra. This agreement and the observed variation of intensities of Kα-X-ray satellites with increasing Z have been the basis for determining and discussing the origin and the identification of observed satellites, which are reported in the literature. As a result, a coherent picture of the origin of Kα-X-ray satellites has emerged.
