Dependence with the oxidation state of X-ray transition energies, intensities and natural line widths of CrKβ spectra

Kβ1,3 line shifts in relation to metallic Cr were observed, both to higher energies (≅+1 eV) for CrIII and to lower energies (≅−0.5 eV) for CrVI. It was also found that the natural width of CrKβ1,3 line, the ionization energy of the 3p orbital of Cr, and the relative intensities of Kβ″ and Kβ2,5 lines with respect to the main Kβ1,3 line increase as the oxidation state increases. The use of these features as an index for chemical state analysis is discussed.
