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. |
