| Outline of Final Research Achievements |
In the evolution of the earth, hydrogen plays many important roles. Hydrogen can be transported within minerals in a fast manner. A small amount of hydrogen dissolves into crystal structures of minerals which greatly changes many physical properties of them; these behaviors are distinctly different from the other elements. These phenomena are understood and predicted by finding atomic-scale diffusion dynamics process of hydrogen in the mineral media. Here we have applied quasielastic neutron scattering for first successfully analyzing the atomic-scale dynamics of hydrogen with the crystal structures of hydrous minerals.
