The partially ionized plasma is described by a model Hamiltonian containing bound (localized) as well as orthogonalized free (itinerant) electron states. The equations of balance for the single particle states are given, and the correlation functions arising in the equations of balance are treatet in the Born approximation. The conductivity is obtained with the aid of the Kohler variational principle. The electron density dependence of the conductivity is presented for different values of the bound state energy level and of the temperature.
