Internal conversion from excited electronic states of ions
Pavlo V. Bilous, Georgy A. Kazakov, Iain D. Moore +2
The process of internal conversion from excited electronic states is investigated theoretically for the case of the vacuum-ultraviolet nuclear transition of . D…
Optical spectroscopy of complex open 4-shell ions Sn-Sn
F. Torretti, A. Windberger, A. Ryabtsev +8
We analyze the complex level structure of ions with many-valence-electron open [Kr] 4 sub-shells (=7-4) with ab initio calculations based on configuration…
Experimental evidence for Wigner's tunneling time
Nicolas Camus, Enderalp Yakaboylu, Lutz Fechner +7
Tunneling of a particle through a potential barrier remains one of the most remarkable quantum phenomena. Owing to advances in laser technology, electric fields comparable to those…
Frequency-comb based collinear laser spectroscopy of Be for nuclear structure investigations and many-body QED tests
A. Krieger, W. Nörtershäuser, Ch. Geppert +13
Absolute transition frequencies of the transitions in Be were measured with a frequency comb in stable and short…
The cross-over from tunnelling to multiphoton ionization of atoms
Michael Klaiber, John S Briggs
We present a theory illuminating the cross-over from strong-field tunnelling ionization to weak-field multiphoton ionization in the interaction of a classical laser field with a hy…
Attosecond physics at the nanoscale
M. F. Ciappina, J. A. Pérez-Hernández, A. S. Landsman +22
Recently two emerging areas of research, attosecond and nanoscale physics, have started to come together. Attosecond physics deals with phenomena occurring when ultrashort laser pu…
Deterministic strong-field quantum control
Stefano M. Cavaletto, Zoltán Harman, Thomas Pfeifer +1
Strong-field quantum-state control is investigated, taking advantage of the full---amplitude and phase---characterization of the interaction between matter and intense ultrashort p…
Weighted difference of g-factors of light Li-like and H-like ions for an improved determination of the fine-structure constant
V. A. Yerokhin, E. Berseneva, Z. Harman +2
A weighted difference of the -factors of the Li- and H-like ion of the same element is studied and optimized in order to maximize the cancellation of nuclear effects. To this en…
Strong higher-order resonant contributions to x-ray line polarization in hot plasmas
Chintan Shah, Pedro Amaro, Rene Steinbrügge +6
We studied angular distributions of x rays emitted in resonant recombination of highly charged iron and krypton ions, resolving dielectronic, trielectronic, and quadruelectronic ch…
The Cryogenic Storage Ring CSR
Robert von Hahn, Arno Becker, Felix Berg +41
An electrostatic cryogenic storage ring, CSR, for beams of anions and cations with up to 300 keV kinetic energy per unit charge has been designed, constructed and put into operatio…
Polarization measurement of dielectronic recombination transitions in highly charged krypton ions
Chintan Shah, Holger Jörg, Sven Bernitt +10
We report linear polarization measurements of x rays emitted due to dielectronic recombination into highly charged krypton ions. The ions in the He-like through O-like charge state…
Influence of orbital symmetry on diffraction imaging with rescattering electron wave packets
M. G. Pullen, B. Wolter, A. -T. Le +9
The ability to directly follow and time resolve the rearrangement of the nuclei within molecules is a frontier of science that requires atomic spatial and few-femtosecond temporal…
Analysis of the fine structure of Sn ions by optical spectroscopy in an electron beam ion trap
A. Windberger, F. Torretti, A. Borschevsky +9
We experimentally re-evaluate the fine structure of Sn ions. These ions are essential in bright extreme-ultraviolet (EUV) plasma-light sources for next-generation nan…
BASE - The Baryon Antibaryon Symmetry Experiment
C. Smorra, K. Blaum, L. Bojtar +17
The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moment…
The electron mass from -factor measurements on hydrogen-like carbon C
Florian Köhler, Sven Sturm, Anke Kracke +3
The electron mass in atomic mass units has been determined with a relative uncertainty of , which represents a 13-fold improvement of the 2010 CODATA value. The…
Transition from non-sequential to sequential double ionisation in many-electron systems
Michael G. Pullen, Benjamin Wolter, Xu Wang +10
Obtaining a detailed understanding of strong-field double ionisation of many-electron systems (heavy atoms and molecules) remains a challenging task. By comparing experimental and…
A tunable low-drift laser stabilized to an atomic reference
Tobias Leopold, Lisa Schmöger, Stefanie Feuchtenbeiner +6
We present a laser system with a linewidth and long-term frequency stability at the 50 kHz level. It is based on a Ti:Sapphire laser emitting radiation at 882 nm which is reference…
