A. Moen et al., SI-O-SI ANGLE DISTRIBUTION IN AMORPHOUS SILICA CHARACTERIZED BY EXAFSMULTIPLE-SCATTERING CALCULATIONS, Journal de physique. IV, 7(C2), 1997, pp. 275-276
EXAFS-Multiple Scattering (MS) calculations has been performed to char
acterize the second shell of neighbours around silicon in amorphous si
lica. To render the large Si-O-Si angle distribution, a combination of
three regular [(Si(OSi)(4)] structural models covering the 130 to 160
degrees angle range is used in the calculations.
