Zusammenfassung: 
Relativistic full-potential photoemission theory, which is a straightforward generalization of the original one-step model, has been applied to photocurrent calculations for the Cu(111) surface. In this paper we present a study of angle-resolved ultraviolet photoemission intensities using excitation with different photon energies. The photoemission investigation is based on a space-filling cell potential which has been determined self-consistently by relativistic full-potential KKR band-structure methods. Our results include muffin-tin as well as full-potential photoemission calculations, which we compare with corresponding experimental data. An improved agreement between experiment and theory is found using full-potential techniques. (C) 1998 Elsevier Science B.V. All rights reserved.
