An evaluation of the Richardson equations for electron emission leads to the most general formulation including the branches of degeneracy, classical statistics, and that of strong photon interaction. The photoelectric yield constant is derived in general form. For black body temperatures above m e c 2 , strong coupling is found generally, while for lower temperatures all three branches exist, depending on the electron density. A confirmation of the consistency of the theory is given by the fact that the quantum process of photoemission does not take more than 5% of the energy density of the black body radiation.
