CINECA IRIS Institutional Research Information System
IRIS è la piattaforma adottata dall’Università degli Studi di Udine per gestire l’archivio aperto dei prodotti della ricerca. L’archivio contiene articoli, contributi in volume, monografie, interventi pubblicati in atti di convegno, Tesi di dottorato e altri materiali.
EnglishWe report the results of an extensive structural study of Na13, Mg13, Al13, and Si13 carried out with the Car-Parrinello method. Several and mostly unforeseen noncrystalline structures are discovered to characterize the low portion of the potential energy surface. Crystalline structures are shown either to correspond to high-energy local minima or to be highly unstable. The low-energy structural pattern appears to change significantly from one element to the other. Specific characteristics as well as trends are discussed.
