Abstract
The energy-loss spectra observed when an electron beam of energy 100 keV and diameter 1-2 nm traverses the face of a small crystal show features which are different from those observed for transmission through thin films. For magnesium oxide smoke crystals having dimensions of 100-700 nm the most prominent features are strong peaks at energy losses of about 17 eV and oscillations in the energy-loss curves with periodicities of 2-5 eV, depending on the crystal dimensions. These features are attributed to energy losses associated with the emission of radiation as the electrons are channeled along the surface with an oscillatory motion and enter and leave the crystal surface region.
