Abstract
We discuss the time dependence of the fourth-order correlation function F(2)(K,Q,τ) which can be measured by ‘‘new’’ dynamic light scattering methods involving the cross correlation of light intensity signals received at two spatially separated detectors which both observe the same small number of correlated regions in a colloidal or polymer solution. F(2)(K,Q,τ) can be regarded as a four-particle generalization of the more familiar two-particle intermediate scattering function F (1)(K,τ).Keywords
