Abstract
The leading curvature correction δ to the surface tension of a spherical interface is defined by γ = γ (0) (1+ δC), where C is the surface curvature. In the framework of the density-functional-theory the values of δ are calculated for cesium and sodium. Semi-empirical estimations of δ are fulfilled for some simple, noble, transition metals and rare gas solids, using evaporation heats per atom and vacancy-formation energies. Numerical results indicate that δ > 0 is in a contradiction with measurements of γ for gold and lead droplets. An attempt of removal of this contradiction is carried out by re-definition of the dividing surface.
