| Abstract: | Abstract Cherenkov radiation emitted from electron irradiated dielectrics such as mica, quartz and BaTiO3 was detected in a transmission electron microscope with the accelerating voltages of 80 kV to 200 kV. Transition radiation was also observed from metals (Al, Ag, Au) and semiconductors (GaAs, Si). Dependence of their intensities and spectra on accelerating voltage and crystal thickness was investigated. |
