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…
Single-Source, Collinear Merged-Beam Experiment for the Study of Reactive Neutral-Neutral Collisions
Katrin Dulitz, Marco van den Beld-Serrano, Frank Stienkemeier
We present two methods for studying reactive collisions between two atomic or molecular species: a collinear merged-beam method, in which two gas pulses from a single supersonic be…
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…
Optical Quenching of Metastable Helium Atoms using Excitation to the State
Jiwen Guan, Vivien Behrendt, Pinrui Shen +5
Discharge and electron-impact excitation lead to the production of metastable helium atoms in two metastable states, 2S and 2S. However, many applications require p…
