✦ Synopsis

The electrical conductivity is investigated for a partially ionized hydrogen plasma, starting from a generalized quantum kinetic equation with three particle collision integrals. To take into account plasma effects, screened potentials are used. The transport croea sections of the considered two and three particle scattering processes are calculated by perturbative solution of the 'Lippmann-Schwinger equations for the T-matrices up to the second Born approximation. In connection with a mass action law the influence of the electron-electron and the elastic electron-atom scattering is discussed. The pressure ionization (Mott-effect) is described by a minimum-behaviour of the electrical conductivity.

Kinetische Naherung der elektrischen Leitfahigkeit in einem partiell ionisierten Wasserstofblelasma

Inhaltsiibersicht. Ausgehend von einer verallgemeinerten quantenkinetischen Gleichung mit 3-TeilchenstoBintegralen wird die elektrische Leitfiihigkeit fiir ein teilweise ionisiertes Wasserstoffplasma untersucht. Urn Plasmaeffekte zu beriicksichtigen, werden abgeschirmte Potentiale benutzt. Die Berechnung der Transportquerschnitte der betrachteten 2und 3-Teilchemtreuprozesse erfolgt durch Storungsentwicklung der Lippmann-Schwinger-Gleichungen fur die T-Matrizen bis zur 2. Bornschen Niiherung. Unter Einbeziehung eines Maasenwirkungsgesetzes wird der EinfluD der Elektron-Elektron-und der elastischen Elektron-Atom-Streuung diskutiert. Die Druckionisation (Motteffekt) wird durch ein Minimumverhalten in der elektrischen Leitfahigkeit beschrieben.

## Abstract Recently it has been shown that in steady‐state situations under certain parameter conditions the conventional Boltzmann equation solution approach using the well known two‐term Legendre polynomial expansion fails to provide a sufficiently accurate description of the energy distribution
