An Enhanced RPA-LDA Model for Ion Stopping Power from Cold Matter to High-Energy Density Plasmas: A Unified, Open-Source Framework
Thomas A. Mehlhorn, Ming Feng Gu, Igor Golovkin
We present an enhanced random-phase-approximation--local-density-approximation (e-RPA-LDA) model for the stopping power of ions that is valid over a wide range of conditions, from…
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…
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…
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…
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, $…
