    Notes: Abstract: Stability of highly charged metal clusters in the electric field of an external ion is investigated with the classical liquid drop model. We study the optimum shape of the cluster which has a local minimum of the total energy, taking account of the effects of the surface charge polarization on the Coulomb energy and the cluster deformation on the surface energy. We find that the cluster deformation greatly affects the total energy of the system and that a cluster with a fissility larger than some critical value 0.7-0.8 can become unstable against deformation. We investigate the local competition between the Coulomb force and the surface tension at the cluster surface and show that the surface charge polarization which is induced by the external electric field significantly affects the shape of the cluster and its stability.

    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.
