Va. Verzilov et al., EXPERIMENTAL INVESTIGATION OF THE CHARACTERISTIC FEATURES OF BREMSSTRAHLUNG FROM HIGH-ENERGY ELECTRONS IN THIN AMORPHOUS TARGETS, JETP letters, 65(5), 1997, pp. 381-385
Radiation from 0-900 MeV electrons in thin amorphous films is investig
ated experimentally in the photon energy range 20-700 keV. The Landau-
Pomeranchuk-Migdal suppression of the soft part of the bremsstrahlung
spectrum and the Ter-Mikaelyan density effect are detected. Coherent b
remsstrahlung on macroscopic inhomogeneities in the target material is
observed. (C) 1997 American Institute of Physics.
