Static electrical conductivity in weak and moderately non-ideal plasmas

Abstract

We present a discussion of semiclassical and quantum mechanical RPA treatments of static electrical conductivity in non-ideal plasmas. It is found that the results obtained from both theories agree well with each other in the range of temperatures from 5000 to 50000 K for electron concentrations between 1018 and 1020 cm-3. The reported results present a significant improvement on the predictions of the Spitzer formula. Good agreement is also found with available experimental data on non-ideal plasmas. An analytical formula for static conductivity for applications is introduced.
