Collision Studies with Laser-Cooled Metastable Helium Atoms - Recoil Atom Spectroscopy. This project will provide the first absolute, differential measurements of the scattering of low energy electrons from metastable excited helium atoms. Laser-cooling techniques are used to create a bright, slow helium beam and a unique approach, where the recoiling atoms are detected, is used for the scattering measurements. Such measurements are of critical importance in the assessment of new scattering theories for excited states and in understanding the role which excited species play in the behaviour of low temperature gas discharges and thus also on the operation of many important devices and phenomena which are based on discharge technology.
