The photoelectron fluxes in cometary atmospheres are calculated by a Monte Carlo method. A pure H2O atmosphere is assumed with a sublimation rate of 10 to the 30th power molecules per sec at 1 AU. Discussions of the energetics of the electron gas and of the elementary collisional processes in determining the fluxes largely concern this water atmosphere. Effects on the photoelectron fluxes are also investigated for CO, another possible constituent. The excitation rate of the 1D level of atomic oxygen in electron impacts is evaluated. It is highly improbable that the photoelectrons are responsible for the observed 6300-A emission of the order of 1 kR at a heliocentric distance of 1 AU. The structure of the heat equation for thermal electrons is analyzed, and a drastic change of the plasma behavior within the coma region is expected.
