Nonergodicity parameters of colloidal glasses

Abstract
Nonergodicity parameters, the nondecaying components of the coherent intermediate scattering functions, of ‘‘hard-sphere’’ colloidal glasses were measured by dynamic light scattering. These agree reasonably well with the predictions of mode-coupling theory for hard-sphere atoms, with no adjustable parameters in the comparison. In addition, we provide further verification of the recently developed theory of dynamic light scattering by nonergodic media.
