Figure 2
Logarithm of the scattering intensity plotted versus q2 for the three samples at room temperature: silica A annealed at 1533 K, measured at room temperature (open circles), sample B (solid line) and sample C (black squares). Comparison with high-temperature measurements (1773 K) (dashed line). This plot exhibits a linear regime at small q values in which extrapolation using equation (5) can be performed. Two examples of linear fits are shown with thin solid lines. |
