Calculation of the Cohesive Energy of Metals by the Fermi-Thomas Method - Communist China -

Abstract

The Fermi-Thomas method is used in this paper to calculate the cohesive energy of metals. The preliminary results obtained indicate that there is a minimum value involved in the relation between the energy and the crystal lattice constant of a metal. For heavy metal, the atomic spacing corresponding to this minimum value are shown to be close to the experimental values; however, for univalent alkali metals, the theoretical values are too small, and the cohesive energies so obtained are much larger than the experimental values. The author tends to think that such discrepancies are due to errors typical in an application of the Fermi-Thomas method to atoms, and that they are not particularly pertinent to the application to metals.
