Lamb dip of a Quadrupole Transition in H
F. M. J. Cozijn, M. L. Diouf, W. Ubachs
The saturated absorption spectrum of the hyperfine-less S(0) quadrupole line in the (2-0) band of H is measured at nm, using the NICE-OHMS technique under cryogenic co…
Novel spin-precession method for sensitive EDM searches
A. Boeschoten, V. R. Marshall, T. B. Meijknecht +10
We demonstrate a spin-precession method to observe and analyze multi-level coherence between all hyperfine levels in the ground state of barium monofluoride (…
Spectroscopic study of the F outer well state in H, HD and D
K. -F. Lai, M. Beyer, W. Ubachs
Two-photon UV-photolysis of hydrogen sulfide molecules is applied to produce hydrogen molecules in highly excited vibrational levels in the \X\ electronic ground state, up to the d…
Rotational level spacings in HD from vibrational saturation spectroscopy
F. M. J. Cozijn, M. L. Diouf, V. Hermann +3
The R(1), R(3) and P(3) ro-vibrational transitions in the (2-0) overtone band of the HD molecule are measured in Doppler-free saturation using the technique of NICE-OHMS spectrosco…
