Crystallography and diffusion dynamics of hydrogen in hydrous minerals by combination analysis of neutron diffraction and quasielastic scattering

Abstract

Hydrogen site geometry in hydrous minerals is important for understanding their water storage mechanism. Diffusion dynamics of hydrogen in these minerals is important for understanding their hydration processes. Here we summarize our recent neutron diffraction and quasielastic scattering results obtained at J-PARC MLF and also at another neutron source, where high-resolution crystallography of hydrogen and its diffusion dynamics were successfully analyzed for various types of hydrous minerals.
