Abstract: The semi-infinite jellium using the step potential model of surface potential is studied. The barrier height is found from the condition of the minimum of the surface energy. It is shown that this minimum is caused by the Coulomb interaction between electrons. The surface energy is positive in the entire domain of the Wigner-Seitz radius of metals, and it is in sufficiently good agreement with experimental data. The one-particle distribution function of electrons and the distance from the surface potential to the dividing plane within this model are calculated. Influence of the Coulomb interaction between electrons on these calculated characteristics is studied.
