Transient structures of solids and liquids by means of time-resolved X-ray diffraction and X-ray spectroscopy

abstract

• We describe a time-resolved x-ray diffraction and EXAFS experimental system, suitable for the study of ultafast processes in liquids and solids, with picosecond time resolution. The system uses a laser pulse to excite the sample and a delayed ultrashort hard x-ray pulse, generated in an x-ray diode driven by the same laser, to probe the structure of intermediate species produced by the excitation. A few time- resolved experiments are described including the picosecond time-resolved x-ray diffraction of laser heated metal and semiconductor crystals, and time-resolved EXAFS of carbon tetrabromide in ethanol solution before and after photoinduced dissociation.
