| Research Abstract |
We propose atomic-resolution coherent X-ray diffraction imaging that combines coherent forward diffraction patterns with coherent Bragg diffraction patterns. In this study, we verified in a computer simulation that atomic-resolution X-ray diffraction imaging is possible when metallic nanocube particles are used as the sample even the current X-ray intensities at the third-generation synchrotron radiation facilitiy, SPring-8. In order to demonstrate the atomic-resolution X-ray imaging, we developed the experimental system for the measurements of coherent Bragg diffraction patterns and succeeded in the collection of (200) coherent diffraction pattern data of a Ag nanocube particle.
