The electron-energy distribution function is calculated for a helium glow discharge at cryogenic temperatures. It is shown that pairwise collisions of metastables increase greatly the fraction of high-energy electrons. The effect of metastables on the integral characteristics of the discharge (excitation rate of the first metastable level and mean energy of the electrons) is discussed. (AIP)
