have examined the optical and spectroscopic difficulties inherent in high-energy atomic-beam spectroscopy experiments. The Doppler effects which result from the high velocity of the beams severely limit the intensity and resolution obtainable in spectroscopic studies of the beams. analyse two possible configurations for collection of light from the beams the first has the optic axis of the spectrograph at 900 to the beam; the second has the optic axis of the spectrograph colinear with the beam direction. The second configuration can lead to greatly enhanced intensity, at a given resolution, over that obtainable with the first. discuss the experimental verification of the analysis. Appendices compare these configurations with another proposed system, and discuss special problems associated with the vacuum ultraviolet.
