Abstract:

The traditional method for studying atomic or molecular collisions is the use of crossed atomic or molecular beams. Owing to the low beam densities one encounters, such studies have generally been restricted to atoms or molecules in ground or metastable states however, it is now possible to use lasers to achieve substantial excited state atomic populations so that scattering from excited states may also be studied in crossed beam experiments. Typically, one obtains the differential scattering cross section as a function of center-of-mass energy in crossed beam experiments. These experiments, although often difficult to perform, provide a direct measure of the scattering process.
