Under certain experimental conditions it is necessary to explain the measurements by assumption of several groups of electrons independent of each other. For such a case the population densities and degress of ionization have been calculated for a steady‐state hydrogen plasma from the coupled system of rate equations. It has been assumed that two independent groups of electrons are present having the density n e and n e * . Further it is assumed that their distribution functions are Maxwellian, so that these groups can be described by temperatures T e and T e * . The calculated population densities and ionization degrees are presented graphically as function of n e * , n e , T e and T e * . A comparison with the measurements of H. Schlüter shows a good agreement.
