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 this experiment, the population distribution for the L-shell magnetic sublevels has been obtained via an angular differential study of the decay photons associated with the subsequent deexcitation process. The results show a very distinctive behavior for the H- and He-like heavy systems. In…

Angular Distribution of Characteristic Radiation Following the Excitation of He-Like Uranium in Relativistic Collisions
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
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 emission from highly charged ions: signatures of magnetic interactions and retardation in strong fields
The electron emission of highly charged ions has been reanalyzed with the goal of separating the magnetic and retardation contributions to the electron–electron (e–e) interaction from the static
State-selective influence of the Breit interaction on the angular distribution of emitted photons following dielectronic recombination
We report a measurement of $KLL$ dielectronic recombination in charge states from Kr$^{+34}$ through Kr$^{+28}$, in order to investigate the contribution of Breit interaction for a wide range of
Polarization measurement of dielectronic recombination transitions in highly charged krypton ions
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 states were populated in
Electron- and proton-impact excitation of heliumlike uranium in relativistic collisions
We have studied the K-shell excitation of He-like uranium (U90+) in relativistic collisions with hydrogen and argon atoms. Performing measurements with different targets, as well as with different ...
