Outline of Final Research Achievements |
For precise structural analysis of particle-filled rubber materials, we have upgraded our instrument of spin contrast variation technique. We have achieved higher proton spin polarization, in turn wider contrast variation, by introducing a high-power microwave source, which stimulates polarization transfer from electron spins to proton spins. The effectiveness of this technique was demonstrated by an experiment at BL15 TAIKAN in J-PARC for rubber materials filled with carbon and silica particles.
