This paper is devoted to the investigation of a turbulent heated beam discharge plasma in the molecular gas hydrogen as an example. We are interested in the stationary behaviour of this plasma type under the condition of weak Langmuir turbulence and under the action of several kinds of interaction processes. This discharge plasma is of increasing importance especially from the point of plasmachemical purposes. At first we give a short development of the kinetic equation employed including the Coulombinteraction between the charged particles as well as the different kinds of binary collision processes between electrons and non‐exited molecules. The essential parameters in this description are the full energy density of the Langmuir turbulence per one electron e 0 Ū = W / n e and the degree of ionization n e / N . In a broad range of these two parameters Ū and n e / N , which are typical for a beam discharge plasma, we determined numerically the velocity distribution function of the electrons and with the aid of this especially the mean energy, the energy gain from the turbulent field, the frequencies for the several collision processes as well as the energy losses due to the binary collisions and the Coulomb interaction between electrons and ions. In particular we investigated the main energy channels by which the energy of the electrons is transfered into the several degrees of freedom of the molecular gas and into the ion component.
