Detection of monochromatic x-ray emission in the interaction of ultrarelativistic electrons with a diamond single crystal
Vorob'ev S. A., Kalinin B. N., Pak S., Potylitsyn A. P.
A yield of monochromatic radiation with an energy of about 19 keV has been detected in the scattering of 600and 900-MeV electrons by the (100) planes of a diamond. The orientational and spectral characteristics that were measured indicate that a parametric (quasi-Cerenkov) x-radiation has been detected for the first time.
