Abstract
The dipole surface plasmon for K(N)+ clusters is analyzed using the RP A sum-rule technique within a semiclassical Density Functional Theory and the spherical jellium model. The theoretical frequencies are blue shifted as compared to the experimental ones. The discrepancies betwee n theory and experiment are reduced when considering non-local energy contributions in the density functional and phenomenologically includi ng atomic lattice effects by means of an electron effective mass and a static dielectric constant.
