| Outline of Final Research Achievements |
At SPring-8 BL11XU, we have developed a nuclear resonant scattering diffractometer (synchrotron Mossbauer diffractometer) by installing θ-2θ goniometer between the nuclear monochromater and a detecting counter. A specific spectrum arising only from a selected γ ray reflection can be measured, which will represent crystal-site-selective Mossbauer spectrum. In order to extract only nuclear resonant scattering, we have established 45 degree-method, polarization analyzer method, and pure nuclear Bragg reflection method. With the use of these three methods, we have succeeded in obtaining crystal-site-selective Mossbauer spectra of typical multi-Fe-site compounds, Fe3O4 and Fe3BO6.
