Rydberg tagging time-of-flight imaging to study 3-body Recombination

With Rydberg tagging time-of-flight imaging of cold atoms, we have achieved a velocity resolution of $\sim $ 2.5 cm/s. This resolution allows accurate measurements of state-to-state differential cross-sections for ultracold collision processes. With the addition of a dipole trap and a Zeeman slower to our current apparatus, these methods may be implemented to study state-to-state differential cross-sections for 3-body recombination to gain insight into the physics of Efimov states. We present data on the current status of our apparatus and ongoing experiments. Detection methods and associated Frank-Condon factors will be presented. \newline
