Abstract. A theoretical study of the Electron Energy Distribution Function (EEDF) in the negative glow of a hollow cathode discharge with cylindrical geometry is proposed. The plasma of a Ne-H2 Penning Recombination Laser is considered. The EEDF is analyzed in the energy region up to several ionization potentials. The spherical part of the EEDF is calculated under the conditions of high current, intermediate pressures and in a mixture of neon and a molecular gas hydrogen. Using EEDF calculated the rate constant for negative hydrogen ion formation is estimated.
