Abstract: The localization length $r_{loc}$ associated with a fast secondary relaxation in glassy Laponite is determined by X-ray photon correlation spectroscopy (XPCS) through a Debye–Waller fit of the non-ergodicity parameter. Quantitative differences are observed between the time dependence (aging) of $r_{loc}$ in spontaneously aged and rejuvenated samples. This behavior is also reflected in the calculated shear modulus which matches well with data obtained by rheological measurements.
