| Outline of Final Research Achievements |
Our research project have been aiming to visualizing experimentally of valence electrons in the material. In order to achieve this project, we have developed experimental as well as analysis method for ultra accurate crystal structure analysis. By these developments, we have succeeded in visualizing anisotropic valence electron distribution which was impossible to visualize of far.
