EN

A variational calculation of the face-dependent work function with pseudopotential corrections employed has been performed. Critical analysis of the comparison between the calculated work function values and the experimental polycrystalline data is also given. The polycrystalline work function data may be treated as the mean low-index work function values and compared with the ones calculated. The use of the simple variational method and the Ashcroft pseudopotential for the description of metallic ions leads to good agreement between theory and experiment, and also enables to explain the increasing or decreasing tendency of work function values in different series of the simple metals.
