Wichmann-Kroll Correction in Muonic Atoms and Hydrogen-Like Electronic Ions: a Comparative Study of Two Methods
Zoia A. Mandrykina, Zewen Sun, Natalia S. Oreshkina
Wichmann-Kroll corrections are calculated in both hydrogen-like electronic ions and muonic systems (--) using two independent methods. The Gaussian finite basis set…
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…
Hadronic vacuum polarization effect in muonic atoms
Zoia A. Mandrykina, Moritz Thierfeld, Natalia S. Oreshkina
The hadronic vacuum polarization (HVP) corrections to energy levels in muonic atoms are studied systematically across the periodic table. Two nuclear charge distribution models hav…
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…
Two-photon Annihilation of Positrons with K-shell Electrons of H-like ions
Z. A. Mandrykina, V. A. Zaytsev, V. A. Yerokhin +1
The two-photon annihilation of a positron with an electron bound in the 1s state of a H-like ion is calculated within the fully relativistic QED framework. The interaction with the…
