Fine structures in Kβ spectra of chromium

A research team led by Professor I. Tsuyumoto (Kanazawa Institute of Technology, Japan) has recently studied chromium Kβ spectra and found that the intensity of Kβ" satellite, which is observed at the higher energy side of the main Kβ_1,3 peak, is strongly correlated with the pre-edge peak of the X-ray absorption near edge structure specific for chromium (VI) compounds, such as CrO₃, Na₂CrO₇・2H₂O, Na₂CrO₄・4H₂O, K₂Cr₂O₇, K₂CrO₄, Zn₂CrO₄(OH)₂・2H₂O, PbCrO₄, and BaCrO₄.
