X-ray and extreme-ultraviolet spectra from collisions of Ar and O ions with neutrals
Stepan Dobrodey, Chintan Shah, Sonja Bernitt +4
We present measurements of K-shell x-ray emission following charge exchange of fully ionized argon with various neutral gaseous targets at small collision energies inside an electr…
Extreme Ultraviolet Superfluorescence in Xenon and Krypton
L. Mercadier, A. Benediktovitch, C. Weninger +19
We present a comprehensive experimental and theoretical study on superfluorescence in the extreme ultraviolet wavelength regime. Focusing a high-intensity free-electron laser pulse…
Laboratory measurements compellingly support charge-exchange mechanism for the 'dark matter' 3.5 keV X-ray line
Chintan Shah, Stepan Dobrodey, Sven Bernitt +4
The reported observations of an unidentified X-ray line feature at 3.5 keV have driven a lively discussion about its possible dark matter origin. Motivated by this, we have m…
Polarization measurement of dielectronic recombination transitions in highly charged krypton ions
Chintan Shah, Holger Jörg, Sven Bernitt +10
We report linear polarization measurements of x rays emitted due to dielectronic recombination into highly charged krypton ions. The ions in the He-like through O-like charge state…
