Materials research by muon.
By using muon, static or dynamic properties of materials are studied. Materials characterization continuously from near surface to bulk and interface with nm-scale depth resolution can be realized by ultra slow muon and we are investigating spin, electronic, and hydrogen states in advanced materials with muon.
Surface nano-structure research by positron beam.
Total-reflection high-energy positron diffraction (TRHEPD) is a surface-sensitive tool owing to the total reflection of positrons, antiparticles of electrons. By making the full use of surface-sensitivity of TRHEPD, we are investigating structure and properties of a two-dimensional atomic sheet such as graphene and silicene.
Materials research by neutron scattering.
Neutron interacts with elementary excitations such as phonon and magnon as a matter wave in materials. At any scattering event, energy and momentum are preserved. Dynamics of elementary excitations can be obtained as a dispersion in E-Q space by studying neutron before and after the scattering. Spin excitation studied by inelastic neutron scattering measurement is shown in the figure.
