Chemical Effects in Kβ/Kα X-Ray Emission Intensities from First-Row Transition Element Compounds

摘要: Chemical effects in x-rays that arise form core transitions are usually small and most investigations have concentrated on precise measurement of the shifts energies peaks. For first-row transition elements perturbations Kα12 Kβ′ Kβ25 been studied for many compounds. Changes peak intensities much less thoroughly investigated, with exception I(Kβ′): I(Kβ13), (I=intensity) which can be roughly correlated number unpaired 3d electrons1. A few years ago it was suggested 2 relative might influenced by chemical state (i.e. valence) ligand environment emitting atom such information could then used to investigate a radioactive recoil solid matrix provided decayed electron capture would followed x-ray emission. Chromium has an isotope work reported there is part systmatic study wide range chromium vanadium Results using non-dispersive techniques already reported3 but claim observed clear variation I(Cr Kβ):I(Cr Kα) Cr valence disputed4.
