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…
Enhanced One-Color-Two-Photon Resonant Ionization in Highly Charged Ions by Fine-Structure Effects
Moto Togawa, Chunhai Lyu, Chintan Shah +25
Ultraintense pulses from X-ray free-electron lasers can drive, within femtoseconds, multiple processes in the inner shells of atoms and molecules in all phases of matter. The ensui…
Laboratory Measurements of Ca XIX Dielectronic Recombination Satellites
Filipe Grilo, Marc Botz, Chintan Shah +3
We report measurements of the K emission from the astrophysically very abundant Ca XIX (He-like ion) and its satellite lines resonantly excited by dielectronic recombination (DR…
Comprehensive Laboratory Benchmark of K-shell Dielectronic Satellites of Fe XXV-XXI Ions
Chintan Shah, Pedro Amaro, Filipe Grilo +7
We report on comprehensive laboratory studies of the K-shell dielectronic recombination (DR) resonances of Fe XXV - XXI ions that prominently contribute to the hard X-ray spectrum…
Hanle effect for lifetime determinations in the soft X-ray regime
Moto Togawa, Jan Richter, Chintan Shah +16
By exciting a series of transitions in helium-like nitrogen ions with linearly polarized mono…
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…
Measurement of differential collisional excitation cross sections for the K emission of He-like oxygen
Filipe Grilo, Chintan Shah, José Marques +3
We measure the energy-differential cross sections for collisional excitation of the soft X-ray electric-dipole K () emission from He-like oxygen (O VII), using an electro…
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, $…
Laboratory Benchmark of Dielectronic Recombination Satellites of Fe XVII
Gabriel J. Grell, Maurice A. Leutenegger, Pedro Amaro +2
We calculated cross sections for the dielectronic recombination (DR) satellite lines of Fe XVII and benchmarked our predictions with experimental cross sections of Fe XVII resonanc…
