| Outline of Final Research Achievements |
We proposed four goals, such as (1): development of neutron holography, (2): light-element imaging, (3): active-site imaging in protein, and (4): sit-selective imaging. Regrading (1), multiple-wavelength neutron holography was successfully demonstrated with the sample of Eu-doped CaF2 single crystal. Moreover, it was applied to the local structure characterization of B-doped materials. Regarding (2), a new apparatus of X-ray fluorescence holography equipped with a small cylindrical graphite analyzer was constructed and it was applied to the imaging of local structures around Ca and K in superconductors. Regarding (3), by introducing liq. N2 flowing system and kai stage, we could establish the method of hologram measurement of proteins under low radiation damage. Then, holograms of hemoglobin and myoglobin proteins were measured to image heme structures around Fe. Regarding (4), using resonant excitation at absorption edges, valence-selective hologram measurements.
