Figure 3
SANS data for a foam prepared from a C14TAB solution (c = 3.5 mM in D2O), measured at different foam heights. (a) h = 7 cm, (b) h = 12 cm, and (c), (d) h = 16.5 cm. Black squares are experimental data. Lines are model fits according to equation (10). For clarity, the full curves (solid red lines) are shown together with the SAS decay (dashed green lines) and the reflectivity contribution (dotted blue lines). In panels (a)–(c) the angle-corrected reflectivity RP(Θ) is applied. Panel (d) was modelled without the angle correction. |
