| Abstract: | The processes by which energetic electrons lose energy in a weakly ionized gas of molecular hydrogen are analysed and calculations are carried out taking into account the discrete nature of the excitation processes. The excitation, ionization and heating efficiencies are computed for electrons with energies up to 100 eV absorbed in a gas with fractional ionizations up to 10?2 and the mean energy per neutral hydrogen atom pair is calculated. |
