Abstract

We have measured the crystal orientation dependence of the intensity of hard photons from Si crystal impinged upon by a 1.2 GeV electron beam. The data are mostly consistent with the theory of coherent radiation except in the close vicinity of the crystal axis, where the data has a sharp peak. The height and width of the anomalous peak are almost constant over the photon energies covered; between 0.2 and 1.1 GeV. In contrast to the similar measurements at Tomsk, no evidence has been found for the suppression of high energy photons around the crystal axis.
