Figure 4
(Top) Time correlation functions, g2(τ), for various translation speeds: 2.5 mm s−1 (black squares); 1.25 mm s−1 (red circles); 0.63 mm s−1 (blue sideways triangles); 0.31 mm s−1 (cyan up triangles); 0.16 mm s−1 (green crosses); 0.08 mm s−1 (magenta Xs). Lines indicate the expected decay due to just the beam transit from equation (4). (Bottom) Time correlation functions, g2(τ), corrected for the effects of translation given in equation (4). Points with uncertainties larger than 10% are not shown. The dashed line is a stretched exponential fit to the data from just the three fastest translation speeds. |
