(a) Neutron total correlation functions, T^N(r), for g-Al₂O₃, l-Al₂O₃³³, and g-SiO₂⁵. (b) X-ray total correlation functions, T^X(r), or g-Al₂O₃, l-Al₂O₃³³, and g-SiO₂⁵. Upper and lower panel data were obtained by Fourier transform with Q_max = 25 and 18 Å⁻¹, respectively. Note that the Al–Al correlation peak is not legibly marked owing to its small weighting factor for neutrons.
