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…
Experiments towards resolving the proton charge radius puzzle
A. Antognini, K. Schuhmann, F. D. Amaro +34
We review the status of the proton charge radius puzzle. Emphasis is given to the various experiments initiated to resolve the conflict between the muonic hydrogen results and the…
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…
Improved X-ray detection and particle identification with avalanche photodiodes
Marc Diepold, Luis M. P. Fernandes, Jorge Machado +36
Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work we report on a fitting technique used to account for different detector responses resulting…
