Sažetak (engleski)

Quite recently the dielectric electronic-response properties of small metal particles were investigated within a strictly self-consistent spherical jellium model. The bottleneck of this kind of calculation for a larger cluster is the self-consistent solution of the single-electron Kohn-Sham equations. Therefore, in this work simple model potentials are investigated and compared with the Kohn-Sham barrier. The result of this comparison is that the widely used model potentials such as finite- or infinite-step potentials are not able to mimic the complex dynamical behavior of a fully self-consistently responding surface.
