Abstract
The spectral weight function of aluminum has been calculated within the local-density approximation. The inclusion of the energy-dependent self-energy has been proved to be important in calculating the single-particle energies, that are in good agreement with experimental data. The main disagreement we found is at theX 1 − level the calculated energy of which is too low. An appreciable lifetime broadening is found with small band dependence and almost parabolic trend as a function of energy.File in questo prodotto:
