Normalized intermediate scattering functions of the SiO2 suspension versus delay time measured at different sample-to-detector distances with (a) q = 8.180 ×10-5 Å and (b) q = 1.420 ×10-4 Å−1. (c) The best-fit decay rate versus wavevector q. Points are the fitting results and the lines are guides to the eye. Data are displaced by a factor of 1.1 for clarity. (d) The best-fit exponent versus wavevector q. Data are displaced by a factor of 1.3 for clarity. |
