Notes: Abstract The electronic energy loss of a positively charged projectile passing through a sodium cluster is calculated by the semiclassical Vlasov method. The electron density before impact is obtained within the localdensity approximation in the jellium model. For the dynamical response, the Vlasov equations are solved by test particle discretization. The model gives the correct breathing mode and dipole Mie frequencies. The energy deposit is calculated as a function of projectile velocity, charge and impact parameter and is compared with theoretical and tabulated values for bulk sodium.

Notes: Abstract. We have measured the static dipole polarizability of lithium and sodium clusters (n=1-22). Values measured for sodium are in agreement with previous experiments. While the polarizability per atom for sodium clusters decreases slowly as a function of the cluster size, a sharp decrease between sizes 1 and 4 is observed for lithium clusters. Experimental values are compared to Density Functional Theory (DFT/PW91) calculations. The size evolutions for sodium and lithium cluster polarizabilities are well reproduced by our calculations. The sharp decrease observed for small lithium clusters is discussed in terms of electronic density.

Notes: Abstract The optical response of alkali metal clusters is shown to be sensitive to a proper treatment of the electronion interaction and to the ionic spatial structure. A spherical symmetry model based on a combination of a geometrical optimization of the ionic structure and the random phase approximation (RPA) with exact exchange is applied to calculate the optical response of Li 139 + . The optical response obtained within this model is in good agreement with the measured giant dipole resonance.
