Abstract
In diluted gases interaction of excess electron with atoms and molecules can be described as a sequence of independent acts of pair scattering. The scattering effect is determined entirely by the cross-section of atom or molecule which knows nothing about the existence of other scatterers. With the density increase this conception losses gradually its validity. Finally in liquid electron interacts at the same time with a number atoms. which are correlated strongly. Moreover electron may loss its high mobility and be captured by density fluctuations. Underline. we consider slow thermal electrons which are in the most degree sensitive to density effects. The goal of theory is to describe not only the electron state in liquid but the gradual changes in its state with the density growth beginning from gas. The peculiarities of electron scattering are clearly displayed in such important observable characteristics as electron mobility in electric field and energy barrier. Hence theory must obtain density dependencies of energy spectrum and mobility.
