Neutralization Dynamics of Slow Highly Charged Ions in 2D Materials

Applied Sciences (Switzerland), 2018
We review experimental and theoretical work on the interaction of slow highly charged ions with two-dimensional materials. Earlier work in the field is summarized and more recent studies on 1 nm thick amorphous carbon nanomembranes and freestanding ...

Long-Lived Levels in Multiply and Highly Charged Ions

Atoms
Atoms and ions remain in some long-lived excited levels for much longer than in typical “normal” levels, but not forever. Various cases of this so-called metastability that occur in multiply or even highly charged ions are discussed in a tutorial review,

g Factor of Few-Electron Highly Charged Ions

Atoms, 2023
The current status of the theoretical investigation of the bound-electron g factor in lithium-like and boron-like highly charged ions is reported. Some tension between the several theoretical values and measurements is discussed.

On Producing Long-Lived Spin Polarized Metastable Atoms—Feasibility of Storing Electric Energy

Atoms, 2022
We describe a method of producing long-lived multiply excited spin polarized atoms or ions, the decay of which is strongly delayed or even blocked by intra-ionic magnetic stabilization.

Spectra of Ga-Like to Cu-Like Praseodymium and Neodymium Ions Observed in the Large Helical Device

Atoms, 2021
Extreme ultraviolet (EUV) spectra of highly charged praseodymium (Pr) and neodymium (Nd) ions have been investigated in optically thin high-temperature plasmas produced in the Large Helical Device (LHD), a magnetically confined torus device for fusion ...

K X-ray Emission for Slow Oxygen Ions Approaching a Copper Metal Surface

Atoms, 2022
We report on the K X-ray emission for 9–140 keV oxygen ions with initial charge states from 3 to 7 approaching a copper surface. The peak center of the measured X-ray spectrum slightly shifts towards higher energies with the increasing of the initial ...

Toward Probing Surface Magnetism with Highly Charged Ions

Atoms, 2022
X-rays produced during collisions between Highly Charged Ions (HCI) and sample surfaces can potentially be used to investigate the surface’s magnetic properties, taking advantage of the (partial) conservation of the spin of the electrons captured by the ...
