Ohoyama Lab. is investigating properties of materials by clarifying atomic and magnetic structures using neutron and other quantum beams. In particular, a characteristic technique we use is "white neutron holography". For such experiments, we often use Japan Proton Accelerator Research Complex, J-PARC (Ibaraki, Japan). Our Lab. is located by the J-PARC, fortunately.
