Doppler-Shifted Reflections of X-Rays in Beam-Foil Spectroscopy,
Abstract
In a conventional beam-foil spectroscopy experiment, radiation from an ion beam is viewed by a spectrometer after the beam has passed through a thin foil. The plane of the foil is usually perpendicular to the ion beam, and the radiation accepted by the spectrometer is emitted in a small range of angles centered about 90 deg. relative to the beam direction. In order to investigate short-lived atomic states excited by the foil, one must view the beam very close to the foil. In a recent experiment, we 'tilted' carbon foils by about 10 deg. relative to the usual perpendicular position to insure that the spectrometer would view the beam as it emerged from the foil, and that no radiation could be shielded by a bowed or wrinkled foil or by the foil holder. We report here the observation of extraneous peaks due to relected radiation in the spectrum obtained with a 'tilted' foil.
