SIMPLE TECHNIQUE FOR OBSERVING QUANTUM BEATS

Abstract
If a luminous particle beam is imaged onto the plane of the entrance slit of a spectrometer, spatial structure in the beam due to quantum beats, decay, etc., appears in each image of the beam in the exit-slit plane. By using a wide entrance slit and a narrow exit slit, and scanning an isolated spectral line, one can observe quantum beats, short lifetimes, etc., without moving the foil, spectrometer, or coupling optics. We have demonstrated this technique using Stark-induced quantum beats in Hβ.
