Extract

The x-ray laser has recently been described (1) as a potentially attractive tool for chemical analysis, both as an improved source for ESCA and also for radiochemistry. The intensity (∼1016 photons/pulse) and associated short exposure time (10-15-10-12 sec) promised are the most attractive features, as is the narrow line width (0.1-0.01 eV). [Such photon fluxes would be equivalent to 1-12 days of exposure with projected electron storage rings (1).] Improved resolution in chemical shift determinations by ESCA are promised as are observations of short-lived excited states and rapid reaction rates in highly-concentrated chemical species. For general utility and optimum analytical capabilities, a photon energy in the 1 keV range from a 10 Å laser would be adequate and is projected (2) to be within the realm of presently conceived technology. Neither a high degree of collimation nor coherence is considered essential although the latter is associated with particularly narrow lines, so that plasma-type noncavity amplified spontaneous emission (ASE) devices (2) will prove adequate.
