Abstract
X-ray photon correlation spectroscopy (XPCS) and dynamic light scattering (DLS) reveal dynamics by interference of coherent scattering, but X-rays permit interrogation of dynamics in a much more diverse array of materials. Heterogeneous dynamics occur in many such materials, and we showed how tools commonly employed in analysis of heterogeneous DLS dynamics extend to XPCS, revealing additional information that conventional Kohlrausch exponential fitting obscures. This work presents the software implementation of inverse transform analysis of XPCS data called CONTIN XPCS, an extension of traditional CONTIN, that accommodates dynamics encountered in equilibrium XPCS measurements.Citation
