Abstract

We have used an intense coherent x-ray beam and a real time digital autocorrelator to study the low frequency dynamics of colloidal palladium in glycerol by x-ray photon correlation spectroscopy (XPCS). The translational diffusion was studied in the q range from 1.5 × 10⁻³ to 6 × 10⁻³Å⁻¹ and in the temperature range from 279 to 293K. The measured relaxation rates were proportional to q² and inversely proportional to viscosity as expected for a translational diffusion process. This experiment shows that XPCS can be performed in a wide time range (10⁻⁴ to 100s) and opens up a new opportunity for the study of the dynamics of nontransparent media.
