Electron and X-ray methods of ultrafast structural dynamics: advances and applications

A review. The state of the art in the detn. of structures with ultrafast electrons and x-rays is highlighted. Perspectives and reflections on the principles, techniques, and methods are provided, and on applications from different disciplines, with some focus on phys., chem., and biol. structures. Although this article is not a survey of all the work done with these techniques, it provides a comprehensive referencing to current research.
