A moderate laboratory magnetic field, Lorentz-boosted into the ion frame, visibly shifts the 1P1 sublevels of He-like Ca and thereby changes the rate, direction, and polarization of resonantly scattered photons.

abstract
Accurate lifetime measurements of excited states of highly charged ions (HCIs) are essential for advancing diagnostics in both laboratory and astrophysical plasmas, especially in the X-ray regime. The Hanle effect, which utilizes external magnetic fields to modify photon scattering patterns, provides a powerful technique for these measurements. Previously, this method has been successfully employed for He-like ions. Here, we present a theoretical study of the prospects of the Hanle effect for lifetime determinations of Li-like ions. Our results highlight the potential for plasma diagnostics and X-ray spectral analysis.

Resonant photon scattering in the presence of external fields and its applications for the Gamma Factory
A moderate laboratory magnetic field, Lorentz-boosted into the ion frame, visibly shifts the 1P1 sublevels of He-like Ca and thereby changes the rate, direction, and polarization of resonantly scattered photons.
