    Notes: Abstract The response of a spherical metallic particle and a void in a metal on an arbitrary external electrical (gradient) field is given analytically within two models: a macroscopic dielectric description in terms of dielectric functions and a linearized hydrodynamic theory which takes into account boundary effects as well as spatial dispersion. From the response functions, the eigenfrequencies of the collective modes and the electron-energy-loss function are obtained. For small radii we found collective modes extending beyond the classical ℓ = ∞ limit of surface-plasmons up to the volume-plasmon. Concerning electron-energy-losses, our results demonstrate that the “blue-shift” on the collective modes which were observed in potassium clusters or calculated for voids in metals are almost of classical origin and stem from spatial dispersion.

    Notes: Abstract. Fabrication of metastable binary solid state film mixtures with continuously variable composition by asymmetric cross-beam PLD is demonstrated. In this technique, the materials are mixed directly in the intersection region of colliding plasmas of individual target materials. This technique can be advantageous for synthesis of solid state quasi-solutions of partially miscible materials, where one can expect interesting mechanic properties and magnetic transformations.
