“…Figure 2(a, plate) presents the experimental points describing the angular distribution of intensity obtained using (vertically) polarized light. The data have been corrected as indicated (Ross et al 1972) and, as an example of the experimental procedure, both the uncorrected and corrected values are indicated. The experimental curve is matched by a superposition of two theoretical angular spectra, corresponding to the correlation functions F 5 = exp (-p2/2a2) for a1 = 320 A (41 = 1 .O) and F 3 = l/(l + (p2/a2)>2 for a2 = 3920 A(qz = 12.3).…”

The paper analyses, from a practical point of view, the light-scattering method used to investigate the structure of polymers (or any other material). The problem of speckle noise is presented and its elimination discussed. Also, the method for obtaining a high resolution in determinations - that is, of increasing the amount of relevant information by sacrificing information which is less relevant - is put forward. A few examples illustrate the approach.

“…In order to carry out light-scattering investigations of many samples there is a requirement for glass cells with very low scattering cross-sections (Ross et al 1972, Ross and Addleman 1973, Addleinan et a1 1975. As this quantity is not commonly defined by the glass manufacturers we have examined in detail the light-scattering properties of several commercial glasses.…”

Light-scattering measurements have been made on optical-quality glass before and after annealing. Small-angle scattering in both specimens indicates the existence of long-range correlations in refractive index of order several hundred nanometres. In addition, wide-angle scatter demonstrates the existence of shorter-range (a few nanometres) correlation distances. All of our observations have been consistent with Goodman's strained mixed cluster model of glasses (1975, 1977). It is shown that the amplitude of the fluctuations is insufficient to support the explanation of the low-temperature (<1K) thermal conductivity of glasses in terms of structural scattering of phonons.
