D. Cabaret et al., FULL MULTIPLE-SCATTERING CALCULATIONS ON SILICATES AND OXIDES AT AL K-EDGE, Journal of electron spectroscopy and related phenomena, 79, 1996, pp. 21-24
We present Full Multiple Scattering calculations at aluminium K-edge t
hat we compare to experiments for four crystalline silicates and oxide
minerals. The purpose of this work is to determine the relation betwe
en Al K-edge spectral features and the geometrical arrangements around
the aluminium sites. In the different minerals aluminium atoms are ei
ther four-fold or six-fold coordinated to oxygen atoms in Al sites tha
t are poorly symmetric. The calculations are based on different choice
s of one-electron potentials according to aluminium coordinations and
crystallographic structures of the compounds.
