Scattering angular

Scattering cro.ss sections have been measured for liquid suspensions of transparent, irregular particles graded in size by sedimentation (Hodkinson, 1966). The shapes of the curves of the scattering cross sections were simpler than those of spherical particles, but

To further understand the structure of these samples, SAXS experiments were carried out and the resulting profiles are shown in Figure 4. The smeared intensity was plotted against the angular scattering variable, s, which is defined as ... 

An example of practical importance in atmospheric physics is the inference of effective optical constants for atmospheric aerosols composed of various kinds of particles and the subsequent use of these optical constants in other ways. One might infer effective n and k from measurements—made either in the laboratory or remotely by, for example, using bistatic lidar—of angular scattering fitting the experimental data with Mie theory would give effective optical constants. But how effectual would they be Would they have more than a limited applicability Would they be more than merely consistent with an experiment of limited scope It is by no means certain that they would lead to correct calculations of extinction or backscattering or absorption. We shall return to these questions in Section 14.2.

Part 3 is a marriage of Parts 1 and 2, the offspring of which are chapters on extinction (Chapter 11), surface modes (Chapter 12), and angular scattering (Chapter 13). Applications are not totally absent from the first thirteen chapters, but there is a greater concentration of them in Chapter 14. 

Angular scattering functions, PIijI, are computed for subchains located in the middle and at the end of a PE chain. The RIS model developed by Flory et at, (S 004 - S 006) is used for the unperturbed chain. Chain expansion is introduced using a matrix treatment which satisfactorily reproduces several configuration-dependent properties of macromolecules perturbed by long-range interactions. 

As can be expected, the angular scattering intensity distribution has become anisotropic. From the data obtained, two values of the average correlation distance between neighboring nodules can be calculated, parallel and perpendicular to the deformation direction respectively. Although the accuracy of the data is not outstanding, it can be seen that d increases with the macroscopic extension ratio, Ax, whereas dx decreases only slightly (Fig. 10). It is not possible to ascertain experimentally whether dL is proportional to AJ1/2 as it should be if the deformation proceeded at constant volume L e., if the network could be considered incompressible.
