Improved laser-EXAFS studies of aluminium foil

Abstract
Using a laser-produced plasma as the X-ray source, and a dispersive spectrometer, EXAFS measurements of Al foil have been made that compare favourably with data obtained using a scanning monochromator and soft X-ray synchrotron radiation. Fourier transform analysis yields a radial distribution function for metallic Al that is realistic out to 6 or 7 AA. Compared with other laser-produced plasma EXAFS studies the present measurements offer a considerable improvement which is attributed to the use of a heavy-metal target.
