Charge radii of Cl isotopes from x-ray spectroscopy of muonic atoms

K. A. Beyer, T. E. Cocolios, C. Costache +25

Nuclear charge radii are vital for nuclear and atomic physics, the determination of fundamental constants, and searches for new physics. Muonic atoms, where a single negative muon…

Towards better nuclear charge radii

István Angeli, Dimiter L. Balabanski, Paraskevi Dimitriou +16

Nuclear charge radii constitute a physical observable of growing significance across multiple subdisciplines of physics and related fields. Their determination relies on a combinat…

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…

Self-consistent bounds on Beyond the Standard Model bosons from spectroscopy of muonic atoms with magic nuclei

K. A. Beyer, N. S. Oreshkina

Spectroscopy of muonic atoms is, to date, the most accurate technique to extract parameters of the nuclear charge density. The same reasons for their heightened sensitivity to nucl…

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…
