    "abstract": "Features of forward diffracted Parametric X-Radiation (PXR) were investigated\nat experiments with the 855 MeV electron beam of the Mainz Microtron MAMI\nemploying a 410 micrometer thick tungsten single crystal. Virtual photons from\nthe electron field are diffracted by the (10-1) plane at a Bragg angle of 3.977\ndegree. Forward emitted radiation was analyzed at an energy of 40 keV with the\n(111) lattice planes of a flat silicon single crystal in Bragg geometry. Clear\npeak structures were observed in an angular scan of the tungsten single\ncrystal. The results were analyzed with a model which describes forward\ndiffracted PXR under real experimental conditions. The experiments show that\nforward diffracted PXR may be employed to diagnose bending radii of lattice\nplanes in large area single crystals.",
