Perspectives

P. Eisenberger, S. Suckewer

Short pulses of x-rays with a time duration comparable to the dynamics of molecules would make a variety of new structural studies possible. In their Perspective, Eisenberger and Suckewer discuss results reported by Schoenlein et al. (p. 236) in the same issue on a new source of subpicosecond x-rays. A short-pulse infrared laser beam is scattered from a beam of high-energy electrons. The radiation scattered from the electrons is in the form of subpicosecond pulses at a wavelength of 0.4 angstrom.
