Does band mapping find its limits in the soft X-ray range?
[La détermination de la structure de bandes trouve-t-elle ses limites dans le domaine des rayons X mous ?]
Comptes Rendus. Physique, Volume 9 (2008) no. 5-6, pp. 517-523.

Nous avons choisi la surface (001) de l'Argent (Ag), qui est un système simple et bien connu, pour étudier le potentiel, en matière d'étude de la structure de bandes, de la spectroscopie de photoémission résolue en angle dans le domaine d'énergie des rayons X mous. Pour déterminer les limites intrinsèques de cette technique, nous avons mesuré la bande de valence de l'argent en fonction de la température et de l'énergie du photon incident. Nous discutons aussi la question des transitions indirectes assistées par phonon.

The (001) surface of Silver (Ag) has been chosen as a simple and well known system for investigating the band mapping potentialities of angle-resolved photoemission spectroscopy in the soft X-ray energy range. In order to determine the intrinsic limits of this technique, the valence band of Ag has been measured both as a function of the measuring temperature and of the incoming photon energy and the issue of phonon-assisted non-direct transitions is addressed.
