| A simple trial function for the electron density profiles at the surface of jellium covered by a submonolayer of alkali adatoms is proposed. The values of work function changes due to adsorption, computed by use of this function, are in good agreement with experimental data. It is shown also that the proposed earlier trial functions for the electron density profiles at the metal surface covered by metallic adlayers, give a wrong sequence of surface concentration of adatoms, at which the minimum of work function for different adsorbates occurs. |
