Reflection extended x-ray absorption fine structure recorded using a laser-produced plasma x-ray source

Abstract
This letter describes the first use of a laser plasma x-ray source for the recording of surface reflection EXAFS (extended x-ray absorption fine structure), or reflexafs. A powerful technique in which a subnanosecond pulse of x rays is used to record the reflection spectrum over a range of incidence angles and wavelengths in a single shot is described. Reflexafs spectra for aluminum are presented which compare favorably with spectra recorded in transmission mode.
