| Outline of Final Research Achievements |
We constructed the experimental apparatus and analysis methods for the three dimensional structural determination of disordered materials using coherent x-ray pulses of free electron laser (X-FEL). We succeeded in the coincidence measurements of small angle x-ray scattering, fluorescence x-ray emission and ion time-of-flight spectra on giant (~200nm) rare-gas clusters at SACLA. Time resolved measurements of X-FEL induced phenomena in sub-ps temporal resolution were achieved by using X-FEL pump – near infrared laser probe method.
The medium-range order (MRO) of room temperature ionic liquids (RTILs), which have the domain structures on the nm spatial scale, was studied by small angle x-ray scattering experiments. We found that the MRO of RTIL is modified by adding the dopant aromatic molecules in a manner that subtly depends on the bonding nature.
