“…where K α /h is the (1s, 2p) contribution to the K x-ray rate, Te is the average energy of the outgoing electron and τ K (U K + Te ) is the K-shell photoionization cross section at the energy U K + Te . Investigation of the KL-RRS and KM-RRS cross sections for xenon atoms was made by Czerwinski et al [26], who found them to be independent from the scattering angle and the polarization state of the incident photons in accordance with the theoretical predictions. For the case of LM-RRS cross sections, their behaviour has not been examined experimentally until now.…”

The resonant Raman effect has been described as an inelastic scattering process occurring when the energy of the exciting x-ray beam approaches from below the energy of an absorption edge of a target element. It produces a scattered photon with a characteristic maximum energy and the emission of an inner-shell electron. A high monochromatic CrK α x-ray beam produced by protons was utilized for the measurement of the KL type of resonant Raman scattering (RRS) cross sections in V and Cr and of the LM ones in La and Ce. In the case of V and Cr targets, the fluorescence yields of the KL-RRS process were also extracted, while the fine-structure splitting in a LM-RRS spectrum was observed for the first time. The influence of RRS into different topics of x-ray spectrometry, like the quantitative x-ray flourescence analysis, the theoretical calculations of the mass attenuation coefficients or the shape of characteristic xrays emitted from low Z thick targets, is also discussed.

Resonant Raman scattering of polarized and unpolarized x-ray radiation from Mg, Al, and Si

The x-ray resonant Raman scattering (RRS) effect of polarized and unpolarized radiation in the vicinity of the 1s absorption threshold of low-Z elements such as magnesium, aluminum, and silicon is investigated. For the polarized and tunable exciting x-ray radiation the plane grating monochromator (PGM) beam line at the PTB laboratory in the BESSY II synchrotron radiation facility was employed, while unpolarized x-ray beams were induced by 1-MeV proton beam irradiation on various pure thick targets. For the latter case, a novel proton-induced x-ray fluorescence scattering chamber was designed and installed at the Tandem accelerator laboratory of the Institute of Nuclear Physics at N.C.S.R. "Demokritos." The total RRS cross sections deduced from both independent excitation modes were found to be in a good agreement, within the experimental uncertainties. The predictions of the existing theory with respect to the dependence of the RRS to the incident beam polarization state is calculated and discussed with respect to the experimental results.
