In this paper, we present an experimental and theoretical study of excitation processes for the heaviest stable helium-like ion, that is, He-like uranium occurring in relativistic collisions with hydrogen and argon targets. In particular, we concentrate on angular distributions of the characteristic Kα radiation following the K → L excitation of He-like uranium. We pay special attention to the magnetic sub-level population of the excited 1s2lj states, which is directly related to the angular…

Ground-state excitation of heavy highly-charged ions

We have studied the excitation of H-like and He-like uranium (U91+ and U90+) in relativistic collisions with gaseous targets by observing the subsequent x-ray emission. The experiment was conducted

Electron- and proton-impact excitation of hydrogenlike uranium in relativistic collisions.

The experimental data clearly demonstrate the importance of including the generalized Breit interaction in the treatment of the EIE process and state-of-the-art calculations performed within the relativistic framework which include excitation mechanisms due to both protons and electrons are in good agreement with the experimental findings.

Magnetic-sublevel population and alignment for the excitation of H- and He-like uranium in relativistic collisions

We have measured the alignment of the L-shell magnetic substates following the K-shell excitation of hydrogen- and helium-like uranium in relativistic collisions with a low-Z gaseous target. Within

The Coulomb excitation of highly charged few-electron ions in relativistic collisions with protons and low-Z atoms is studied within the framework of first-order perturbation theory and the

Shell- and subshell-resolved projectile excitation of hydrogenlike Au78+ ions in relativistic ion-atom collisions

The projectile excitation of high-Z ions has been investigated in relativistic ion-atoms collisions by observing the subsequent x-ray emission. The x-ray spectra from the projectile excitation have

Excitation of heavy hydrogenlike ions by light atoms in relativistic collisions with large momentum transfers

We present a theory for excitation of heavy hydrogen-like projectile-ions by light target-atoms in collisions where the momentum transfers to the atom are very large on the atomic scale. It is shown

Excitation of highly charged hydrogenlike ions by the impact of equivelocity electrons and protons: A comparative study

Abstract We consider excitation of highly charged hydrogen-like ions by the impact of equivelocity electrons and protons. The kineticenergy of the protons is more than three orders of magnitude

The generalized Breit interaction is included in the scattering matrix elements when determining collision strengths for electron-impact excitation of highly charged ions and effects for the more complex He-like and Li-like ions are greater than for the hydrogenic analogs for the entire range of values considered.
