Gas kinetic approach for electron mobility in dense media

Abstract
The motion of electrons in nonpolar dense media is studied in the framework of gas kinetic transport theory. The observed external electric field dependence of electron mobility is explained by means of the solution of Boltzmann-type transport equation. Numerical calculations of the mobility, mean energy, and energy distribution function of electrons in liquid Ar and in liquid CH4 are presented and a good agreement with experimental data is obtained. Also the cases of gaseous Ar are studied.
