Abstract
In this contribution we report first results from a study of aqueous protei n-polymer solutions using the complementary techniques of quasielastic neut ron scattering (QENS) and photon correlation spectroscopy (PCS). A 15% solu tion of bovine serum albumin (BSA) without and with 10% PEO600 (polyethylen e oxide, M-w = 600) is used as a model system to study changes in proton mi cro-diffusivity by analysing QENS broadenings at low and high momentum tran sfers.
