Profile

Mössbauer spectroscopy is one of the most powerful methods providing deep insights into atomistic nature (valence state, chemical bond, spin state, etc.) for various kinds of materials using nuclear probes without perturbations, and therefore, has widely been applied to scientific researches since the discovery of the Mössbauer effect in 1958. On the other hand, since the first clear experiment of nuclear resonance scattering of synchrotron radiation (SR) at Hamburg in 1985, SR-based Mössbauer spectroscopy has extensively been developed, which allows us to measure various kinds of Mössbauer spectra whose observation is difficult by using ordinary radioactive sources. Moreover, in addition to Mössbauer spectra, the measurement of element specific vibrations has become possible using nuclear resonant inelastic scattering. These cutting-edge techniques have attracted much attention in the wide scientific fields such as material science, physics, chemistry, biology, earth science, etc.

Main purpose of our present research to transfer the central knowledge of Mössbauer spectroscopy not only to the next generations but also to the scientists working in other research fields. The second purpose was to exchange the present overview of new methodologies developed at different synchrotron facilities, and share the future perspectives for the Mössbauer spectroscopic method and related techniques. The third purpose was to shed the light on advanced materials such as battery and other energy materials investigated by Mössbauer spectroscopy. The fourth purpose was to focus on the imaging techniques in Mössbauer spectroscopy and their applications to various kinds of materials.
