Tackling the uncertainty of the nuclear-polarization correction to the bound-electron factor by means of the nuclear Skyrme interaction
Arnab Choudhury, Igor A. Valuev
The paper evaluates the nuclear‑polarization correction to the bound‑electron g factor of hydrogenlike ions using Skyrme‑based Hartree‑Fock random‑phase approximation calculations…
Relativistic recoil as a key to the fine-structure puzzle in muonic
Konstantin A. Beyer, Igor A. Valuev, Zoia A. Mandrykina +2
The long-standing fine-structure anomaly in muonic Zr is resolved through a rigorous treatment of the relativistic-recoil effect. From a fit of ab initio QED calculations of…
Pb nuclear charge radius revisited: closing the fine-structure-anomaly gap
Zewen Sun, Konstantin Beyer, Zoia A. Mandrykina +3
A comprehensive reevaluation of the root-mean-square nuclear charge radius is presented for the doubly magic Pb extracted from muonic spectroscopy measurements. By integrat…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
