Determination of electrical conductivity of plasma on the basis of the cut-off Coulomb potential model

In the case of low temperature and large electron density the Debye model potential is not the correct tool for describing the plasma microfields and to calculate the electric conductivity. The screened (cut-off) Coulomb potential is very useful for the interpretation of experimental data. The fitting procedure is described in detail in the case of fully ionized hydrogen plasma. The parameters of the calculation are tabulated, thus they can be easily used for estimation. (D.Gy.)
