Anomalous elastic scattering of an x-ray photon by a molybdenum atom near the K-edge

The differential cross section and dispersional correction for the real par t of the elastic scattering amplitude of an x-ray photon by a molybdenum at om in the energy range of the ionization threshold of the 1s-shell is calcu lated in the non-relativistic approximation. The effect of the rearrangemen t of electron shells of the atomic residues in the field of the virtual 1s- vacancy is taken into account. The processes of one-photon multiple excitat ion/ionization of the ground state is also considered. Good agreement with the results of existing experiments is obtained.
