Quantum Electrodynamics in Strong Electromagnetic Fields: Substate Resolved K Transition Energies in Helium-like Uranium
Philip Pfäfflein, Günter Weber, Steffen Allgeier +34
Using novel metallic magnetic calorimeter detectors at the CRYRING@ESR, we recorded X-ray spectra of stored and electron cooled helium-like uranium (U) with an unmatched sp…
X-ray emission associated with radiative recombination for Pb ions at threshold energies
B. Zhu, A. Gumberidze, T. Over +28
For bare lead ions, decelerated to the low beam energy of 10 MeV/u, the x-ray emission associated with radiative recombination (RR) at "cold collision" conditions has been studied…
Swirling the weakly bound helium dimer from inside
Maksim Kunitski, Qingze Guan, Holger Maschkiwitz +9
Controlling the interactions between atoms with external fields opened up new branches in physics ranging from strongly correlated atomic systems to ideal Bose and Fermi gases and…
Towards experiments with highly charged ions at HESR
Rodolfo Sánchez, Angela Braeuning-Demian, Jan Glorius +9
The atomic physic collaboration SPARC is a part of the APPA pillar at the future Facility for Antiproton and Ion Research. It aims for atomic-physics research across virtually the…
Crystal growth rates in supercooled atomic liquid mixtures
Alexander Schottelius, Francesco Mambretti, Anton Kalinin +11
Crystallization is a fundamental process in materials science, providing the primary route for the realization of a wide range of new materials. Crystallization rates are also cons…
Double-slit photoelectron interference in strong-field ionization of the neon dimer
Maksim Kunitski, Nicolas Eicke, Pia Huber +13
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental c…
