Precision Measurements in Few-Electron Molecules: The Ionization Energy of Metastable $^{4}$ He $_{2}$ and the First Rotational Interval of $^{4}$ He $_{2}^{+}$

Luca Semeria, Paul Jansen, Gian-Marco Camenisch +3

Molecular helium represents a benchmark system for testing $ab initio$ calculations on few-electron molecules. We report on the determination of the adiabatic ionization e…

Precision measurement of the rotational energy-level structure of the three-electron molecule He $_{2}^{+}$

Luca Semeria, Paul Jansen, Frédéric Merkt

The term values of all rotational levels of the $^{4}$ He $_{2}^{+} X^{+}^{2} Σ_{u}^{+} (ν^{+} = 0)$ ground vibronic state with rotational quantum number $N^{+} \leq 19$ have been determined with an…

High-resolution spectroscopy of He $_{2}^{+}$ using Rydberg-series extrapolation and Zeeman-decelerated supersonic beams of metastable He $_{2}$

Paul Jansen, Luca Semeria, Frédéric Merkt

Recently, high-resolution spectroscopy of slow beams of metastable helium molecules (He $_{2}^{*}$ ) generated by multistage Zeeman deceleration was used in combination with Rydberg-seri…
