Physical review letters, 2008•APSThe intermediate scattering function (ISF) is measured for a colloidal hard-sphere glass as
functions of the scattering vector and waiting time. For scattering vectors near the structure
factor peak, we show that the ISF and the stretching index, defined at the crossover time
between the fast and slow processes, depend algebraically on the waiting time. By contrast,
the Debye-Waller factor is independent of the waiting time.
