The existence of an evanescent x-ray wave, which decays exponentially with distance into the film, and of a standing x-ray wave with a large and varying period has been demonstrated clearly in the region of total external reflection from a Langmuir-Blodgett film. The standing wave can be utilized to obtain structural information about multilayer organic systems.
