Multi-electron processes in K-shell double and triple photodetachment of oxygen anions
30th International Conference on Photonic, Electronic and Atomic Collisions, ICPEAC XXX, CairnsCairns, Australia, 26 Jul 2017 - 1 Aug 20172017-07-262017-08-01 Journal of physics / Conference Series 875, 022004 () [10.1088/1742-6596/875/3/022004]
Absolute cross sections for double and triple photodetachment of O− ions have been measured at photon energies around the threshold for K-shell ionization using the photon-ion merged-beams technique at a synchrotron light-source. In addition, corresponding large-scale ab-initio calculations were carried out at a level of complexity that has never been invoked before. [...]

Accessing the hyperfine splitting in highly charged helium-like ions via angle-resolved x-ray spectroscopic analysis
30th International Conference on Photonic, Electronic and Atomic Collisions, ICPEAC XXX, CairnsCairns, Australia, 26 Jul 2017 - 1 Aug 20172017-07-262017-08-01 Journal of physics / Conference Series 875, 022043 - () [10.1088/1742-6596/875/3/022043]
A new scheme is presented for determining the hyperfine splitting of highly charged ions via angle-resolved spectroscopic analysis. In particular, we propose two measurements on the angular distribution and linear polarization of the emission line 1s2p 3 P 1, F = I − 1, I, I + 1 → 1s 2 1 S 0, Ff = I of He-like isotopic ions, following the stimulated decay of the 1s2s 1 S 0, Fi = I level.

Sideband and streaking regimes in two-color photoionization by twisted X-waves in strong infrared fields
30th International Conference on Photonic, Electronic and Atomic Collisions, (ICPEAC XXX, CairnsCairns, Australia, 26 Jul 2017 - 1 Aug 20172017-07-262017-08-01 Journal of physics / Conference Series 875, 022017 - () [10.1088/1742-6596/875/3/022017]
The photoionization by short twisted XUV pulses (X-waves) is investigated in the presence of an intense infrared beam within the S-matrix formalism. It is demonstrated how sidebands are affected by the twist of the ionizing pulse as the pulse duration increases..

The spin evolution of two spin-1/2 valence electrons, located at two separated ions, is investigated with the help of Breit equation. This evolution that arise solely depends on their dipole-dipole magnetic interaction. [...]

Shake-up processes in Auger Cascades of Light and Medium Elements
30th International Conference on Photonic, Electronic and Atomic Collisions, ICPEAC XXX, CairnsCairns, Australia, 26 Jul 2017 - 1 Aug 20172017-07-262017-08-01 Journal of physics / Conference Series 875, 062004 - () [10.1088/1742-6596/875/7/062004]
Many-electron computations are applied to model the de-excitation of inner-shell excited atoms by a cascade of Auger decays. In particular, the effects of shake-up transitions on Auger cascades of different elements are discussed together with various theoretical models that are needed to account for the underlying electron-electron correlations..

Polarization reconstruction algorithm for a Compton polarimeter
FAIR next geenration scientists - 5th Edition Workshop, FAIRness 2017, SitgesSitges, Spain, 28 May 2017 - 3 Jun 20172017-05-282017-06-03 Journal of physics / Conference Series 1024, 012041 () [10.1088/1742-6596/1024/1/012041]
We present the technique of Compton polarimetry using X-ray detectors based on double-sided segmented semiconductor crystals that were developed within the SPARC collaboration. In addition, we discuss the polarization reconstruction algorithm with particular emphasis on systematic deviations between the observed detector response and our model function for the Compton scattering distribution inside the detector..
