“…the density, and Z and M, the atomic number and mass, respectively). It follows that the ratio between the intensity scattered by the wet sample, I wet (q), and the dry sample, I dry (q), is equal to 0.28 with d carbon ) 2 g/cm 3 and using the value of the liquid density for benzene (the same value is obtained for m-xylene). The dash-dotted curve plotted in Figure 7, overlapping I dry (q) in the middle of the q domain, corresponds to a shift F exp equal to 4.2, that is, C exp ) 0.24, which is larger than the expected C e .…”
