| Outline of Final Research Achievements |
Diamond nano particle (DNP) is expected to be a new neutron reflector material because it has huge scattering cross section due to its form factor. In recently, chemically-pure and uniform-sized DNP can be provided inexpensively, hence application of DNP as neutron reflector takes on a reality.
DNP is powdery with bulk density of ~0.5 g/cm3. We succeeded to increase the bulk density up to 1.1 g/cm3 by applying pressure of 150 MPa. We measured the differential cross section. The differential scattering cross section was about 2,500 times more than single 12C nucleus due to the coherent scattering.
