Kavčič, Matjaz Žitnik, M. Sokaras, D. Weng, T.-C. Alonso-Mori, R. Nordlund, D. Dousse, Jean-Claude Hoszowska, Joanna 2014-08-21 High-energy-resolution photoexcited KN2,3 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. application/pdf https://folia.unifr.ch/global/documents/303799 https://folia.unifr.ch/documents/303799/files/dou_hrx.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevA.90.022513 info:eu-repo/semantics/openAccess License undefined Physical Review A. - 2014, vol. 90, no. 2, p. 022513 info:eu-repo/classification/udc/53 High-resolution x-ray-emission study of 1s4p and 1s3d two-electron photoexcitations in Kr http://purl.org/coar/resource_type/c_6501
