Translational cooling and storage of protonated proteins in an ion trap at subkelvin temperatures
D. Offenberg, C. B. Zhang, Ch. Wellers +2
Gas-phase multiply charged proteins have been sympathetically cooled to translational temperatures below 1 K by Coulomb interaction with laser-cooled barium ions in a linear ion tr…
Measurement of small photodestruction rates of cold, charged biomolecules in an ion trap
D. Offenberg, Ch. Wellers, C. B. Zhang +2
In this work, we demonstrate measurements of photodestruction rates of translationally cold, charged biomolecules. The long-term stable storage of the molecular ions in an ion trap…
Precision Spectroscopy of Molecular Hydrogen Ions: Towards Frequency Metrology of Particle Masses
B. Roth, J. Koelemeij, S. Schiller +4
We describe the current status of high-precision ab initio calculations of the spectra of molecular hydrogen ions (H_2^+ and HD^+) and of two experiments for vibrational spectrosco…
Sympathetic cooling of He ions in a radiofrequency trap
B. Roth, U. Fröhlich, S. Schiller
We have generated Coulomb crystals of ultracold He ions in a linear radiofrequency trap, by sympathetic cooling via laser--cooled Be. Stable crystals containing up…
