Large-angle coherent χ radiation associated with the so-called parametric χ radiation (PXR) is observed from a mosaic pyrolytic graphite crystal using a low electron beam energy: 5.7 MeV. The 1-st order (002) PXR reflection results in emission of photons with energies peaked near 14 keV, at a large angle 6>D=28° with respect to electron beam. © 1995 American Institute of Physics.
