Abstract

The \ensuremath{\alpha}-relaxation dynamics in a hard-sphere system is studied solving microscopic-mode-coupling equations. The solutions for coherent and incoherent dynamical structure factors, the transversal correlation functions, and the moduli are presented for all wave vectors. The wave-vector dependence of fitted Kohlrausch exponents \ensuremath{\beta} and of the relaxation times \ensuremath{\tau} is discussed. Recent experiments on the \ensuremath{\alpha} relaxation of colloidal systems are quantitatively analyzed.
