| Popis: | Near an absorption edge, x-ray emission cannot be treated separately from the absorption process itself; a scattering formalism must be used. Experimental data have been recorded showing x-ray emission from xenon following excitation by tunable synchrotron radiation below and above the {ital L}{sub 3} absorption edge. Complete data sets are presented for Xe {ital L}{alpha}{sub 1,2} and {ital L}{beta}{sub 2,15} emission from 10 eV below to 40 eV above the {ital L}{sub 3} edge. In accord with the resonant-inelastic-scattering model, the observed x-ray emission evolves from resonant Raman scattering into characteristic fluorescence as the excitation energy is scanned from below to above the absorption edge. |
