Outline of Final Research Achievements

Time-resolved Diffracted Neutron Tracking (DNT) can observe dynamical single molecules by using labelled micro-crystals. Until now, we're successful to observe dynamical single molecules by using X-rays and Electrons. Single molecule tracking techniques using 3 big quantum beams will make them be completed by this study result. In order to decide the material of detectable and labelled micro-crystal, the neutron diffraction of the gold micro-crystal and the diamond micro-crystal was performed. As a result, it was revealed that a crystal of a micro diamond (0.1 micron) was very sensitive by an experimental beam line of J-PRAC (NOVA BL21).
