Figure 6
Plots over temperature from 20 to 838 K for α-quartz using both anisotropic displacement ellipsoids (`anisotropic DW') and an isotropic Debye model with Debye temperature 470 K for all atoms (`isotropic DW'). DW stands for Debye–Waller. X-rays of 10 000 eV energy are used. (a) The squared magnitude of the structure factors of [(10\overline 11)_{{\rm dextro}{\hbox{-}}z(+)}] and [(10\overline 1\overline 1)_{{\rm dextro}{\hbox{-}}z(+)}]. (b) The phase angle in radians of the structure factor of [(10\overline 1\overline 1)_{{\rm dextro}{\hbox{-}}z(+)}]. (c) The phase angle in radians of the structure factor of [(10\overline 11)_{{\rm dextro}{\hbox{-}}z(+)}].
