| Research Abstract |
An ultrafast X-ray diffraction measurement system has been built up by using a pulsed X-ray source generated with the focusing of femtosecond laser pulses onto a suitable target. The system was utilized for measuring transient lattice changes of a few semiconductor and copper sulfate penta-hydrate crystals induced with photo-excitation. In addition, it has been shown that changes in the radial distribution function due to structural changes of photochromic molecules can be obtained from X-ray scattering patterns of the solution including the molecules as solutes.
