Self-Consistent Energy Bands of Silver by an Augmented-Plane-Wave Method

The band structures, Fermi surfaces, and density of states from two self-consistent augmented-plane-wave calculations of silver are presented and compared with previously reported results. The full Slater exchange term was used in one of these calculations, and $\frac{5}{6}$ of the Slater term was used in the other. Comparison with experimentally obtained data indicates that the calculation having the exchange reduced to $\frac{5}{6}$ yields the better results.
