摘要：

We analyze the Wigner distribution function of spherical alkali-metal clusters in the framework of the Density Functional Theory formalism using the jellium and the pseudopotential-jellium models. Nonlocal effects of the interaction between the ionic cores and the set of valence electrons are discussed in comparison with the jellium prediction. We show that simple models like the Slater approach with surface diffuseness give the main features and reproduce the first moments of the Wigner distribution function and can also be used to analyze large clusters.
