Probing the local structure of liquid binary mixtures by x-ray absorption spectroscopy

摘要: Local structure of binary mixtures has been usually determined by diffraction techniques. In the past few years analysis x-ray absorption spectroscopy data proved to be a powerful tool for an accurate determination solid and liquid systems, complementary or neutron scattering methods. this paper we report about procedure extract pair correlation functions disordered from fine (XAFS) data, satisfying both long-distance behavior long wavelength limit Bhatia-Thornton factors. An application XAFS collected on $\mathrm{CuSn}$ metal alloy $(\mathrm{Cu}6\mathrm{Sn}5)$ is reported compared with existing models.
