Outline of Final Research Achievements

Atomic resolution neutron holography technique is the unique neutron scattering experiments for local structure investigations, which is important for visualization of local structures around dopants in functional materials. In this projects, we aims at practical application of Atomic resolution neutron holography technique using the high flux white neutron beam in J-PARC. We have succeeded in obtaining more than 100 holograms in J-PARC and visualizing clear local structure around dopant Eu in CaF2, which is a typical scintillation crystal. This clearly indicates that neutron holography with white neutron beam is effective for investigations of doped functional materials. In this meaning, we succeeded in achieving the purpose of this project.
