We have developed a method to measure simultaneously the internal energy of bulk and the first layeratoms of a crystal. The internal energy of bulk and the surface atoms of lithium (110) have beenevaluated from 22 K up to above the melting transition, applying the Debye model to the thermalbroadening of the respective 1s photoemission lines. Our measurements clearly reveal two phasechanges: the known liquid to solid transition and the surface melting, occurring 50 K below the bulkmelting point.

Abstract
We have developed a method to measure simultaneously the internal energy of bulk and the first layeratoms of a crystal. The internal energy of bulk and the surface atoms of lithium (110) have beenevaluated from 22 K up to above the melting transition, applying the Debye model to the thermalbroadening of the respective 1s photoemission lines. Our measurements clearly reveal two phasechanges: the known liquid to solid transition and the surface melting, occurring 50 K below the bulkmelting point.File in questo prodotto:
