An all-optical atom trap as a target for MOTRIMS-like collision experiments
S. Sharma, B. P. Acharya, A. H. N. C. De Silva +5
Momentum-resolved scattering experiments with laser-cooled atomic targets have been performed since almost two decades with MOTRIMS (Magneto-Optical Trap Recoil Ion Momentum Spectr…
Ultracold anions for high-precision antihydrogen experiments
G. Cerchiari, A. Kellerbauer, M. S. Safronova +2
Experiments with antihydrogen () for a study of matter--antimatter symmetry and antimatter gravity require ultracold to reach ultimate pr…
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.…
Laser-induced electronic bridge for characterization of the nuclear transition with a tunable optical laser
Pavlo V. Bilous, Ekkehard Peik, Adriana Pálffy
An alternative method to determine the excitation energy of the isomer via the laser-induced electronic bridge is investigated theoretically. In the presence…
Sympathetic Cooling of Protons and Antiprotons with a Common Endcap Penning Trap

Photodetachment thermometry on a beam of OH in a cryogenic storage ring cooled to below 10 K is carried out using two-dimensional, frequency and time dependent photodetachment…
Analytical approach to Coulomb focusing in strong field ionization
Jiří Daněk, Karen Z. Hatsagortsyan, Christoph H. Keitel
The role of the Coulomb potential of the atomic core for creation of caustics in the photoelectron momentum distribution for tunneling ionization in a linearly polarized strong las…
High-precision measurement of the proton's atomic mass
Fabian Heiße, Florian Köhler-Langes, Sascha Rau +9
We report on the precise measurement of the atomic mass of a single proton with a purpose-built Penning-trap system. With a precision of 32 parts-per-trillion our result not only i…
Electron-correlation effects in the -factor of light Li-like ions
V. A. Yerokhin, K. Pachucki, M. Puchalski +2
We investigate electron-correlation effects in the -factor of the ground state of Li-like ions. Our calculations are performed within the nonrelativistic quantum electrodynamics…
Observation and Control of Laser-Enabled Auger Decay

Single photon laser enabled Auger decay (spLEAD) has been redicted theoretically [Phys. Rev. Lett. 111, 083004 (2013)] and here we report its first experimental observation in neon…
Under-the-tunneling-barrier recollisions in strong field ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
A new pathway of strong laser field induced ionization of an atom is identified which is based on recollisions under the tunneling barrier. With an amended strong field approximati…
