Research Abstract

The purpose of the present study is to do a feasibility study of the imaging of a d-electron orbit by using J-PARC high-energy neutron and Synchrotron radiation of Photon Factory at KEK. In order to do experiment, we had reconstructed SENJU at J-PARC and tested the machine using standard samples after the large earthquake at March 11, 2011. The result is satisfactory and we found the accessible Q-value is greatly extended compared with the reactor-based experiment. We have developed a new methodology for X-ray diffraction experiments and performed the measurement of YTiO3 at Photon Factory synchrotron radiation. As a result, we could successfully obtained a d-electron image around Ti atom.
