Molecular structure retrieval directly from laboratory-frame photoelectron spectra in laser-induced electron diffraction
A. Sanchez, K. Amini, S. -J. Wang +12
Ubiquitous to most molecular scattering methods is the challenge to retrieve bond distance and angle from the scattering signals since this requires convergence of pattern matching…
An ultralow-noise superconducting radio-frequency ion trap for frequency metrology with highly charged ions
J. Stark, C. Warnecke, S. Bogen +17
We present a novel ultrastable superconducting radio-frequency (RF) ion trap realized as a combination of an RF cavity and a linear Paul trap. Its RF quadrupole mode at 34.52 MHz r…
The Heidelberg compact electron beam ion traps
P. Micke, S. Kühn, L. Buchauer +16
Electron beam ion traps (EBIT) are ideal tools for both production and study of highly charged ions (HCI). In order to reduce their construction, maintenance, and operation costs w…
Photoelectron spectroscopy of laser-dressed atomic helium
Severin Meister, Aaron Bondy, Kirsten Schnorr +10
Photoelectron emission from excited states of laser-dressed atomic helium is analyzed with respect to laser intensity-dependent excitation energy shifts and angular distributions.…
High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen
M. A. Leutenegger, S. Kühn, P. Micke +25
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…
Electronic bridge excitation in highly charged Th-229 ions
Pavlo V. Bilous, Hendrik Bekker, Julian Berengut +6
The excitation of the 8 eV Th isomer through the electronic bridge mechanism in highly charged ions is investigated theoretically. By exploiting the rich level scheme of o…
