Characterization of the electronic ground state of He $_{2}^{+}$ 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 $_{2}$ have Rydberg character. Their potential-energy functions are simi…

Laser cooling Rydberg molecules -- a detailed study of the helium dimer

Lucía 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 $_{2}^{*}$ would enable a new generat…

Precision measurement of the last bound states in H $_{2}$ and determination of the H + H scattering length

K. -F. Lai, W. Ubachs, M. Beyer

The binding energies of the five bound rotational levels $J = 0 - 4$ in the highest vibrational level $v = 14$ in the X $^{1} Σ_{g}^{+}$ ground electronic state of H $_{2}$ were measured in a three…

The Rotational and Spin-Rotational Level Structure of para-H $_{2}^{+}$ from High-Resolution MQDT-Assisted Rydberg-State Spectroscopy

I. Doran, M. Beyer, F. Merkt

The structure of the low-lying rotational levels of the X $^{+}$ $^{2} Σ_{g}^{+}$ ( $v^{+} = 0$ ) vibronic ground state of para-H $_{2}^{+}$ has been determined by combining frequency-comb calibrate…
