Paper Abstract

The present review describes the application of Doppler spectroscopy to studies in collision dynamics. The method was originally introduced by Kinsey. We used it to obtain angular and velocity distributions of Ba(6s6p1P1) atoms scattered in the 6s6p3P2 level by collisions with Argon and simple molecules. After a short review of our recent work, we outline those areas where Doppler spectroscopy is a valuable tool (sometimes the only tool) for exploring gas phase collision dynamics. In particular we make clear the Doppler spectroscopy should not be considered as alternative but rather as complementary to the standard way of measuring differential cross sections where a rotating mass spectrometer rather than laser induced fluorescence is used to detect the scattered particles.
