Quantum interference in laser spectroscopy of highly charged lithiumlike ions
Pedro Amaro, Ulisses Loureiro, Laleh Safari +4
We investigate the quantum interference induced shifts between energetically close states in highly charged ions, with the energy structure being observed by laser spectroscopy. In…
Quantum interference shifts in laser spectroscopy with elliptical polarization
Pedro Amaro, Filippo Fratini, Laleh Safari +4
We investigate the quantum interference shifts between energetically close states, where the state structure is observed by laser spectroscopy. We report a compact and analytical e…
Relativistic evaluation of the two-photon decay of the metastable ${1s}^{2} 2s 2p~^3\mbox{P}_0$ state in berylliumlike ions with an active-electron model
Pedro Amaro, Filippo Fratini, Laleh Safari +4
The two-photon ${1s}^{2} 2s 2p~^3\mbox{P}_0 \rightarrow {1s}^{2} {2s}^2$ $^1\mbox{S}_0$ transition in berylliumlike ions is theoretically investigated within a full relativistic fr…
Quantum interference effects in laser spectroscopy of muonic hydrogen, deuterium, and helium-3
Pedro Amaro, Beatrice Franke, Julian J. Krauth +9
Quantum interference between energetically close states is theoretically investigated, with the state structure being observed via laser spectroscopy. In this work, we focus on hyp…
Spin effects probed by Rayleigh X-ray scattering off hydrogenic ions
Laleh Safari, Jose Paulo Santos, Pedro Amaro +1
We study the polarization characteristics of x-ray photons scattered by hydrogenic atoms, based on the Dirac equation and second-order perturbation theory. The relativistic states…
Angular and polarization analysis for two-photon decay of 2s hyperfine states of hydrogenlike Uranium
Laleh Safari, Pedro Amaro, Jose Paulo Santos +1
The amplitude of two-photon transitions between hyperfine states in hydrogenlike ions is derived based on relativistic Dirac equation and second order perturbation theory. We study…
