Abstract
In the nonrelativistic approximation for one-electron wave functions, the d ifferential cross section for anomalous scattering of linearly polarized X- ray emission by a sodium atom near the ionization threshold of the 1s(2) Sh ell is studied. The analysis takes into account the many-body effects of re laxation of atomic shells in the field of a deep vacancy, multiplet splitti ng, and the double excitation/ionization processes. The theoretical results obtained for the anomalous-dispersion scattering region are predictive. (C ) 2000 MAIK "Nauka/Interperiodica".
