Journal Article

We present measurements of interspecies thermalization between ultracold samples of 133Cs and either 174Yb or 170Yb. The two species are trapped in a far-off-resonance optical dipole trap and 133Cs is sympathetically cooled by Yb. We extract effectiv...

We investigate the effect of far-off-resonant trapping light on ultracold bosonic 87Rb133Cs molecules. We use kHz-precision microwave spectroscopy to measure the differential AC~Stark shifts between the ground and first excited rotational levels of t...

Experimental measurements and theoretical calculations are reported for rotational energy transfer in the Ar-CO system. Experiments were performed in cold uniform supersonic flows of Ar, using an infrared – vacuum ultraviolet double resonance techniq...

Magnetic trapping of SH radicals (2017)
Journal Article
Eardley, J., Warner, N., Deng, L., Carty, D., & Wrede, E. (2017). Magnetic trapping of SH radicals. Physical Chemistry Chemical Physics, 19(12), 8423-8427. https://doi.org/10.1039/c7cp00458c

Magnetic trapping of SH radicals, produced via the photostop technique, has been demonstrated. H2S in a skimmed, supersonic molecular beam was photodissociated at 212.8 nm to produce SH inside a 330 mK deep static magnetic trap. The molecular-beam sp...
