IMPEDANCE-MATCHED GRAZING-INCIDENCE FILMS - PURE NUCLEAR REFLECTIONS, RESONANT FILTERING OF SYNCHROTRON RADIATION, AND X-RAY INTERFEROMETRY

The purpose of the Letter is to point out the possibility of a new interference technique in x-ray and γ-ray optics-the simple idea of impedance-matched grazing-incidence films-and to discuss applications to pure nuclear coherent reflections, resonant filtering of synchrotron radiation, and x-ray interferometry. © 1979 The American Physical Society.
