Cerenkov Radiation in the Neighborhood of the Emission Threshold. Revised

Abstract

Cerenkov radiation for constant velocity electrons in an infinite uniform dielectric has a sharp threshold for v (electron) larger than the speed of light in the dielectric. A medium of finite length produces diffraction which smears the Cerenkov emission angle and lowers the threshold velocity for emission.
