Abstract :
The calculations of the electron transport coefficients (electron mobility, diffusion coefficient, mean energy and characteristic energy) and the electron drift velocity in liquid Xenon have been carried out taking into account the space correlation of atoms and the density dependent effective scattering cross section of electrons in dense medium. The obtained transport coefficients are functions of electric field strength. The functions differ from those for electrons in dilute Xe gas. The drift velocity of electrons in liquid is a constant for high fields and it approaches to values in gas with the field strength increasing. This rule is not valid for electron diffusion in the liquid: value of the diffusion coefficient in the liquid is larger than its values in the gas for high fields.
