Nonlinearities of King's plot and their dependence on nuclear radii
Robert A. Müller, Vladimir A. Yerokhin, Anton N. Artemyev +1
Investigations of isotope shifts of atomic spectral lines provide insights into nuclear properties. Deviations from the linear dependence of the isotope shifts of two atomic transi…
Sensitivity to New Physics of Isotope Shift Studies using the Coronal Lines of Highly Charged Calcium Ions
Nils-Holger Rehbehn, Michael K. Rosner, Hendrik Bekker +8
Promising searches for new physics beyond the current Standard Model (SM) of particle physics are feasible through isotope-shift spectroscopy, which is sensitive to a hypothetical…
Vacuum polarization and finite nuclear size effects in the two-photon decay of hydrogen-like ions
J. Sommerfeldt, R. A. Müller, A. V. Volotka +2
The total two-photon decay rate of hydrogen-like ions is studied using relativistic quantum electrodynamics. In particular, we analyse how finite nuclear size and QED vacuum polari…
Resonant sequential two-photon ionization of atoms by twisted and plane-wave light
V. P. Kosheleva, V. A. Zaytsev, R. A. Müller +2
We study the resonant sequential two-photon ionization of neutral atoms by a combination of twisted- and plane-wave light within a fully relativistic framework. In particular, the…
Generalized excitation of atomic multipole transitions by twisted light modes
S. A. -L. Schulz, A. A. Peshkov, R. A. Müller +5
A theoretical study is performed for the excitation of a single atom localized in the center of twisted light modes. Here we present the explicit dependence of excitation rates on…
Polarization effects in bound-free pair production
J. Sommerfeldt, R. A. Müller, A. N. Artemyev +1
We present a theoretical study of bound-free electron-positron pair production in the interaction of -rays with bare ions. Special attention is paid to the longitudinal polariza…
Elastic scattering of twisted electrons by diatomic molecules
A. V. Maiorova, S. Fritzsche, R. A. Mueller +1
The elastic scattering of twisted electrons by diatomic molecules is studied within the framework of the non-relativistic first Born approximation. In this process, the coherent in…
Hyperfine interaction with the Th nucleus and its low lying isomeric state
Robert A. Müller, Anna V. Maiorova, Stephan Fritzsche +8
The thorium nucleus with mass number has attracted much interest because its extremely low lying first excited isomeric state at about eV opens the possibility for the d…
Theoretical analysis of the electron bridge process in Th
Robert A. Müller, Andrey V. Volotka, S. Fritzsche +1
We investigate the deexcitation of the Th nucleus via the excitation of an electron. Detailed calculations are performed for the enhancement of the nuclear decay width due…
The effect of bound state dressing in laser assisted radiative recombination
Robert Alexander Müller, Daniel Seipt, Stephan Fritzsche +1
We present a theoretical study on the recombination of a free electron into the ground state of a hydrogen-like ion in the presence of an external laser field. Emphasis is placed o…
