Semiclassical variational calculation of liquid-drop model coefficients for metal clusters

  • Published:
Zeitschrift für Physik D Atoms, Molecules and Clusters

Abstract

We report on semiclassical density variational calculations for spherical alkali metal clusters in the jellium model. We derive liquid-drop model expansions for total energy, ionisation potential and electron affinity and test the coefficients numerically for clusters with up toN=105 atoms. From the limitN→∞, we obtain excellent agreement with surface tensions and work functions evaluated for an infinite plane metal surface.
