| Outline of Final Research Achievements |
Neutron diffraction measurements were carried out by employing newly constructed high-intensity high-performance neutron spectrometer NOVA installed at the J-PARC. New scientific insights on the solution structure in the atomic level were obtained for I. Hydration structure of Li+ in diluted aqueous LiNO3, LiCl and LiClO4 solutions. II. Concentration dependence of Na+ hydration structure by means of neutron-X-ray simultaneous analyses of interference terms obtained from H-rich sample solutions. A new method for the inelasticity correction for the Time-of-Flight neutron diffraction was developed. III. Details of the solvation structure of Li+ were determined for concentrated LiPF6-dimethylcarbonate, LiCl and LiClO4-tetrahydrofuran, and LiTFSA-tetraglyme solutions.
