Abstract

We describe a wholly spectroscopic technique in which the state-to-state differential scattering cross-section is determined for rotationally inelastic atom-molecule collisions. The method uses two single frequency tunable dye lasers in a sub-Doppler double resonance experiment. The method has the added advantage that dependence on initial velocity may be determined. The method is illustrated for the case of rotational transfer in Li₂ - Xe collisions.
