The Theory of Cerenkov Line Radiation

by Vincent Keung Chan


The theory of Cerenkov line radiation is investigated. New equations for Cerenkov line emissivity and refractive index of less dense medium are derived. The applicaiton of the theory in explainng steep Balmer decrements in quasars is investigated and comments are made. The Doppler broadening of Cerenkov lines in warm gas is calculated and its effect on reducing the intensity of Cerenkov emission lines is discussed.
