Spin-state-controlled chemi-ionization reactions between metastable helium atoms and ground-state lithium atoms
Tobias Sixt, Frank Stienkemeier, Katrin Dulitz
We demonstrate the control of He(2S)-Li(2S) chemi-ionization reactions by all-optical electron-spin-state preparation of both atomic species prior to th…
Sensitive detection of metastable NO and \ce{N2} by reactive collisions with laser-excited Li
Jiwen Guan, Tobias Sixt, Katrin Dulitz +1
In a proof-of-principle experiment, we demonstrate that metastable nitric oxide molecules, NO(a), generated inside a pulsed, supersonic beam, can be detected by reactive gas…
Preparation of individual magnetic sub-levels of He(S) in a supersonic beam using laser optical pumping and magnetic hexapole focusing
Tobias Sixt, Jiwen Guan, Alexandra Tsoukala +4
We compare two different experimental techniques for the magnetic-sub-level preparation of metastable He in the S level in a supersonic beam, namely magnetic hexapole…
Buffer-gas cooling, high-resolution spectroscopy and optical cycling of barium monofluoride molecules
Ralf Albrecht, Michael Scharwaechter, Tobias Sixt +2
We demonstrate buffer-gas cooling, high-resolution spectroscopy and cycling fluorescence of cold barium monofluoride (BaF) molecules. Our source produces an intense and internally…
