✦ Synopsis
Sulfur Ka,., X-ray transitions are calculated for a series of systems using the equivalent-cores approximation in which sulfur with a core hole is replaced by a Cl+ ion. Charge densities on such chlorine atoms are evaluated using the INDO method and correlated with experimental transition energies. The position of Ku,,~ lines which cannot be resolved experimentally are predicted. A qualitative explanation of valence orbital penetration into the atomic core and the resulting effects on X-ray spectra is presented,
