It has been established that atomic beams are useful diagnostic tools in the study of plasmas. They are well suited for certain measurements of plasma ion velocity distributions, and have been used, through attenuation experiments, to measure plasma densities and temperatures. This paper considers the possibility of extending the application of atomic beams to the detection of collective effects in laboratory plasmas. The incident beam energy, even for thermal beams, may be much greater than the energies which characterize the interacting plasma. This suggests that for a wide class of beam energies a weak binding approximation can be used to describe the scattering. In this paper, attention is confined to one such approximation - the impulse approximation. Author
