Abstract (German)

Eine Erweiterung von Gutzwillers semiklassischer "Theorie der periodischen Bahnen" auf Systeme mit kontinuierlichen Symmetrien wird verwendet, um Aussagen über die Grundzustandsdeformationen von einfachen Metallclustern zu machen, die im Rahmen des Schalenmodells beschrieben werden. Die durch die semiklassischen Näherungen bedingten Einschränkungen der Theorie werden diskutiert und Möglichkeiten ...

Translation of the abstract (English)

An extension of Gutzwiller's semiclassical "Periodic Orbit Theory" for systems with continous symmetries is used to predict the ground state deformations of simple metal clusters which are described in the framework of the shell model. Restrictions of the theory caused by the semiclassical approximations are discussed and possible generalizations are demonstrated. The results are compared with corresponding quantum mechanical calculations.
