Journal Article
Doherty, W., Bell, M., Softley, T., Rowland, A., Wrede, E., & Carty, D. (2011). Production of cold bromine atoms at zero mean velocity by photodissociation. Physical Chemistry Chemical Physics, 13(18), 8441-8447. https://doi.org/10.1039/c0cp02472d

The production of a translationally cold (T < 1 K) sample of bromine atoms with estimated densities of up to 108 cm−3 using photodissociation is presented. A molecular beam of Br2 seeded in Kr is photodissociated into Br + Br* fragments, and the velo... Read More about Production of cold bromine atoms at zero mean velocity by photodissociation.

A molecular synchrotron (2007)
Journal Article
Heiner, C., Carty, D., Meijer, G., & Bethlem, H. (2007). A molecular synchrotron. Nature Physics, 3(2), 115-118. https://doi.org/10.1038/nphys513

Many of the tools for manipulating the motion of neutral atoms and molecules take their inspiration from techniques developed for charged particles. Traps for atoms—akin to the Paul trap for ions1—have paved the way for many exciting experiments, ran... Read More about A molecular synchrotron.

Alternating gradient focusing and deceleration of polar molecules (2006)
Journal Article
Bethlem, H., Tarbutt, M., Kupper, J., Carty, D., Wohlfart, K., Hinds, E., & Meijer, G. (2006). Alternating gradient focusing and deceleration of polar molecules. Journal of Physics B: Atomic, Molecular and Optical Physics, 39(16), R263-R291. https://doi.org/10.1088/0953-4075/39/16/r01

Beams of polar molecules can be focused using an array of electrostatic lenses in alternating gradient (AG) configuration. They can also be accelerated or decelerated by applying an appropriate high-voltage switching sequence to the lenses. AG focusi...
