Journal ArticleDOI
Determination of small level splittings in highly charged ions via angle-resolved measurements of characteristic x rays
Z. W. Wu,Z. W. Wu,N M Kabachnik,N M Kabachnik,Andrey Surzhykov,Chenzhong Dong,Stephan Fritzsche,Stephan Fritzsche +7 more
TL;DR: In this paper, small energy-level splittings of resonance states in highly charged ions can be extracted from the angular correlations of characteristic x rays emitted in radiative cascades.
Journal ArticleDOI
Many-electron effects on x-ray Rayleigh scattering by highly charged He-like ions
TL;DR: In this article, the authors investigated the many-electron effects beyond the independent-particle approximation (IPA) as conventionally employed for describing the Rayleigh scattering of x-rays by highly charged ions.
Journal ArticleDOI
Hyperfine-induced effects on the linear polarization of the K$\alpha_1$ emission from helium-like ions
Andrey Surzhykov,Andrey Surzhykov,Yuri A. Litvinov,Thomas Stöhlker,Thomas Stöhlker,Stephan Fritzsche,Stephan Fritzsche +6 more
TL;DR: In this article, the linear polarization of the characteristic photon emission from few-electron ions is studied for its sensitivity with regard to the nuclear spin and magnetic moment of the ions.
Journal ArticleDOI
Neon in ultrashort and intense x rays from free electron lasers
Christian Buth,R. Beerwerth,R. Beerwerth,Razib Obaid,Nora Berrah,Lorenz S. Cederbaum,Stephan Fritzsche,Stephan Fritzsche +7 more
TL;DR: In this article, the authors theoretically examine neon atoms in ultrashort and intense x rays from free electron lasers and compare their results with data from experiments conducted at the Linac Coherent Light Source (LCLS) using a relativistic multiconfiguration approach.
Journal ArticleDOI
Hyperfine-induced modifications to the angular distribution of the K α 1 x-ray emission
TL;DR: In this article, the angular distribution of the x-ray emission following the radiative electron capture into initially hydrogenlike ions with nonzero nuclear spin has been studied within the density matrix theory and the multiconfiguration Dirac-Fock method.
