The derivation of the cellulose microfibril angle by small-angle X-ray scattering from structurally characterized softwood cell-wall populations

Figure 9
Variation of the azimuthal scattering angle [Phi]

for a microfibril in a cell wall as the angle [alpha]

between the normal to the cell wall and the direction of the X-ray beam increases (see Fig. 5

). The fitted curve is the function [Phi]

tan^-1(cos [alpha]

tan31°).
