Abstract in Undetermined

Core-level binding energy shifts between the free atomand corresponding large clusters, the latter closely

approximating the infinite solid, have been experimentally derived for several elemental metals. The

cluster core-level binding energies in question have been determined relative to the vacuum level using

synchrotron-based photoelectron spectroscopy. As expected, the experimental shift values show reasonable

agreement with those calculated using the thermochemical Born–Haber cycle approach. The largest

uncertainty factors defining the discrepancies between the experiment and the model, such as the difference

in the multiplet structure of free atoms and the solid, the in some cases indirectly established cluster

work functions, and the metal solvation energy, are discussed.
