Abstract
An approximate formula, derived via a particular "glue" model of interatomi c forces, is brought into direct contact with experiment for close-packed m etals Cu, An and Ni. Thereby, two vacancy properties, mono-vacancy formatio n energy and divacancy binding energy, are shown to correlate approximately with a specific combination of surface energies. Best accord with the theo retical prediction is found for Ni. (C) 2000 Elsevier Science Ltd. All righ ts reserved.
