Investigation of unbound hydrogen isotopes with the Gamow shell model

H. H. Li, J. G. Li, N. Michel +1

Although they are part of the lightest nuclei, the hydrogen isotopes are not well understood both experimentally and theoretically. Indeed, besides deuteron and triton, all known h…

Investigation of isospin-symmetry-breaking in mirror energy difference and nuclear mass with ab initio calculations

H. H. Li, Q. Yuan, J. G. Li +7

Isospin-symmetry breaking is responsible for the energy difference of excited states in mirror nuclei. It also influences the coefficient of the isobaric multiplet mass equation. I…

Access to the kaon radius with kaonic atoms

Niklas Michel, Natalia S. Oreshkina

We put forward a method for determination of the kaon radius from the spectra of kaonic atoms. We analyze the few lowest transitions and their sensitivity to the size of the kaon f…

The measurement of the quadrupole moment of 185-Re and 187-Re from the hyperfine structure of muonic X rays

A. Antognini, N. Berger, T. E. Cocolios +23

The hyperfine splitting of the 5g -> 4f transitions in muonic 185,187-Re has been measured using high resolution HPGe detectors and compared to state-of-the-art atomic theoretical…

Higher-order corrections for the dynamic hyperfine structure of muonic atoms

Niklas Michel, Natalia S. Oreshkina

A method for precise calculation of the energy corrections due to second order electric quadrupole interactions, as well as mixed electric quadrupole-vacuum polarization in the fra…

Non-perturbative analysis of nuclear shape effects on the bound electron g factor

Niklas Michel, Jacek Zatorski, Natalia S. Oreshkina +1

The theory of the g factor of an electron bound to a deformed nucleus is considered non-perturbatively and results are presented for a wide range of nuclei with charge numbers from…

Access to improve the muon mass and magnetic moment anomaly via the bound-muon factor

B. Sikora, H. Cakir, N. Michel +6

A theoretical description of the factor of a muon bound in a nuclear potential is presented. One-loop self-energy and multi-loop vacuum polarization corrections are calculated,…

Theoretical prediction of the Fine and Hyperfine structure of heavy muonic atoms

Niklas Michel, Natalia S. Oreshkina, Christoph H. Keitel

Precision calculations of the fine and hyperfine structure of muonic atoms are performed in a relativistic approach and results for muonic 205 Bi, 147 Sm, and 89 Zr are presented.…

Hyperfine splitting in simple ions for the search of the variation of fundamental constants

Natalia S. Oreshkina, Stefano M. Cavaletto, Niklas Michel +2

Numerous few-electron atomic systems are considered which can be used effectively for observing a potential variation of the fine-structure constant and the electron-proton mas…

Influence of ion movement on the bound electron g-factor

Niklas Michel, Jacek Zatorski, Christoph H. Keitel

In the relativistic description of atomic systems in external fields the total momentum and the external electric field couple to the angular momentum of the individual particles.…

Finite size effects and the order of a phase transition in fragmenting nuclear systems

J. M. Carmona, N. Michel, J. Richert +1

We discuss the implications of finite size effects on the determination of the order of a phase transition which may occur in infinite systems. We introduce a specific model to whi…
