Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishThe capability of grazing angle (e,2e) experiments to map momentum distribution is demonstrated.: This is an application of reflection (e,2e) experiments as a unique twofold spectroscopy, binding energy and momentum distribution, for solid surfaces. The reported experiments have been performed on highly oriented pyrolytic graphite at about 300-eV incident energy, grazing angle, and for ejected electron energies ranging from 3.7 to 30 eV. These experiments, interpreted in the framework of the plane-wave impulse approximation, yield the binding energy vs momentum dispersion curves of valence electron states as well as the individual pi-state momentum density. Both results compare favorably with calculated graphite band structure. [S0163-1829(98)06404-2].
