Resonance inelastic scattering of a photon by the neon atom in the region of the K and KL23 ionization thresholds

摘要

The influence of multiparticle effects on the shape and absolute values of the double differential cross section of the resonance inelastic scattering of a linearly polarized x-ray photon by the neon atom in the energy region of the K and KL23 ionization thresholds is studied theoretically. The radial relaxation of electronic shells, the spin-orbit and multiplet splittings, the configuration interaction in the states of double excitation of the atom, and the Auger and radiative decays of vacancies formed are taken into account. The calculation results are predictive in character and agree well with experiment for an incident photon energy equal to 5.41 keV.
