“…Since the photon absorption is described by the one-electron operator, these multiple excitations cannot be described within the independent electron picture and are possible only due to electron-electron interactions and therefore directly probe the correlations between electrons. The presence of satellite lines in the photoinduced x-ray-emission [1][2][3], Auger [4], or photoelectron spectra [5][6][7] provides evidence for such multielectron photoexcitations. At photon energies high above the excitation threshold the production of satellite lines is explained by the shake model using sudden approximation [1].…”

High-energy-resolution photoexcited KN 2,3 x-ray-emission measurements were carried out on krypton with the excitation energy tuned around the 1s4p and 1s3d double-excitation thresholds. Comprehensive two-dimensional resonant inelastic x-ray-scattering maps were recorded for the range of excitation and emission energies corresponding to both types of double excitations. The double-excitation signal could be clearly resolved from the dominant 1s ionization signal. The latter was subtracted from the measured maps, yielding isolated 1s4p and 1s3d photoexcitation spectra. Both two-electron excitation spectra are well described by a model spectrum built of consecutive bound-bound discrete transitions and shake-up and shake-off channels giving precise energies and intensities of the corresponding contributions. The obtained results are compared with other existing experimental values based on x-ray-absorption measurements and theoretical predictions.

“…While RIXS is hindered by relatively lower resolution and spectral intensity in the soft x-ray regime compared to resonant-Auger spectroscopy, it has recently been shown to provide very detailed dynamical information in the 2-10 keV photon energy range, including the 1s thresholds of Ar and Cl and 2p threshold of I [32][33][34][35]. As reported by Simon et al [33] and Carniato et al [34] measurements of KL lines using RIXS take advantage of the ultrafast dynamics and high-energy-resolution decay spectra with long-pulse light sources using the concept of effective duration time of the scattering process [36,37].…”

Angular and dynamical properties in resonant inelastic x-ray scattering: Case study of chlorine-containing molecules

et al. 2012

Polarization-dependent resonant inelastic x-ray scattering (RIXS) has been shown to be a probe of molecularfield effects on the electronic structure of isolated molecules. In this experimental analysis we explain the linear dichroism observed in Cl 2p polarized RIXS following Cl 1s excitation of a series of chlorofluoromethanes (CF 3 Cl, CF 2 Cl 2 , CFCl 3 , and CCl 4 ) as due to molecular-field effects, including singlet-triplet exchange. We present an approach to extract directly the 2p inner-shell electronic state populations from the experimental measurements. Using the angular properties of the measured KV emission we also are able to determine the value of the polarization anisotropy parameter β p for each resolved component of the KV emission spectra.

The electron-induced L 3 M two-step double ionization cross sections of metallic Pd were determined experimentally for incident electron beam energies ranging from the double ionization threshold up to 18 keV. The double L 3 M ionization cross sections were derived from the intensity ratios (I LαM :I Lα ) of the resolved M satellites to the parent diagram lines. The sample was bombarded with monoenergetic electrons from an energy-tunable 20-kV electron gun. The diagram and M-satellite x-ray lines were measured by means of high-resolution x-ray spectroscopy, using a reflection-type von Hamos bent crystal spectrometer. The two-step partial cross sections were determined by subtracting from the measured total double ionization cross sections the contributions due to the shake process and L 1 -L 3 M 4,5 Coster-Kronig transitions. Despite the thick target employed in the present study, the dependence of the two-step cross sections on the incoming electron energy could be derived using a target slice decomposition method. It is shown that the obtained energy dependence can be well reproduced by the semiempirical parametrization model of Pattard and Rost.
