Transition Radiation from NiO, CoO and MnO

Abstract

The visible radiation emitted from the single crystals of NiO, CoO and MnO by the fast electron bombardment is investigated. The spectral distributions, the angular distributions of the intensity, the polarization characteristics of the emitted light were measured. The experimental results are discussed in view of the theoretical prediction of the transition radiation as well as other possibilities caused by the fast electron bombardment. It is concluded that this radiation is the transition radiation predicted by Frank and Ginsburg.
