摘要：
Asymmetry indices, chemical shifts and full widths at half maximum intensity (FWHM) of the chromium Kalpha1 and Kalpha2 x-ray emission lines were studied in chromium metal, some of its divalent, trivalent, tetravalent and hexavalent compounds, and minerals, catalysts and glassy materials by an x-ray fluorescence excitation method. The asymmetry indices were found to depend on the number of unpaired 3d electrons. The chemical shifts, spin-orbit splittings, asymmetry indices and the half-widths of both the X-ray emission lines show interesting trends with the oxidation state of chromium.
