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…
High-accuracy Measurements of Core-excited Transitions in Light Li-like Ions
Moto Togawa, Steffen Kühn, Chintan Shah +11
The transition energies of the two -core-excited soft X-ray lines (dubbed q and r) from to the respective upper levels an…
Natural-linewidth measurements of the 3C and 3D soft-x-ray transitions in Ni XIX
Chintan Shah, Steffen Kühn, Sonja Bernitt +15
We used the monochromatic soft-x-ray beamline P04 at the synchrotron-radiation facility PETRA III to resonantly excite the strongest transitions in neon-like Ni XIX ions, $…
High-Precision Transition Energy Measurements of Neon-like Fe XVII Ions
Chintan Shah, Moto Togawa, Marc Botz +15
We improve by a factor of 4-20 the energy accuracy of the strongest soft X-ray transitions of Fe XVII ions by resonantly exciting them in an electron beam ion trap with a monochrom…
Integration of maXs-type microcalorimeter detectors for high-resolution x-ray spectroscopy into the experimental environment at the CRYRING@ESR electron cooler
Ph. Pfäfflein, S. Bernitt, Ch. Hahn +17
We report on the first integration of novel magnetic microcalorimeter detectors (MMCs), developed within SPARC (Stored Particles Atomic Physics Research Collaboration), into the ex…
New Measurement Resolves Key Astrophysical Fe XVII Oscillator Strength Problem
Steffen Kühn, Charles Cheung, Natalia S. Oreshkina +19
One of the most enduring and intensively studied problems of X-ray astronomy is the disagreement of state-of-the art theory and observations for the intensity ratio of two Fe XVII…
