Anregung und Ionisation eines Wasserstoffplasmas unter dem Einfluß zweier Elektronengruppen unterschiedlicher Temperatur und Dichte

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.
