The Stark effect in molecular Rydberg states: Calculation of Rydberg-Stark manifolds of H and D including fine and hyperfine structures
Ioana Doran, Leon Jeckel, Maximilian Beyer +2
We present a general theoretical treatment and calculations of the fine and hyperfine structures in the spectra of high- molecular Rydberg states in static uniform electric fiel…
State-selected preparation of molecular ions for precision measurements in radio-frequency traps
Daniel Y. Knapp, Maximilian Beyer
The application of mass-analyzed threshold ionization (MATI) for the state-selective preparation of molecular ions is presented. Based on photoexcitation of long-lived high- Ryd…
Characterization of the electronic ground state of He by high-resolution photoelectron spectroscopy
M. Holdener, V. Wirth, N. A. Shahin +2
Excluding the very shallow potential minimum of the electronic ground state, all bound electronic states of He have Rydberg character. Their potential-energy functions are simi…
Laser cooling Rydberg molecules -- a detailed study of the helium dimer
LucÃa Verdegay, Bingcheng Zeng, Daniel Y. Knapp +2
The helium dimer in its metastable triplet state is a promising candidate to be the first laser-cooled homonuclear molecule. An ultracold gas of He would enable a new generat…
Precision measurement of the last bound states in H and determination of the H + H scattering length
K. -F. Lai, W. Ubachs, M. Beyer
The binding energies of the five bound rotational levels in the highest vibrational level in the X ground electronic state of H were measured in a thre…
