| dc.description.abstract | In this Work the question is wether there is a change in the photoelectronspectra for the both coinage metals, silver and copper, und hydration. For this purpose the clusters are artificially made, separated by mass and finally examined by photoelectronspectroscopy. A second topic is the feature of the bining of hydrogen to aluminium cluters due to Li et al.: aluminium clusters form with hydrogen according to the Wade-Mingos-Rules compounds similar the boranes. In this work we consinder the exchange of the hydrogen in this compounds by its isotope deuterium. To perform the this experiments a whole new experiment was set up. It consists of the three necessary components of the cluster physic: a cluster source, a time-of-flight-massspectrometer, and a photoelectronspectrometer. | eng |

| kops.description.abstract | Im Zuge dieser Arbeit wird geklärt, ob sich eine Änderung der Photoelektronenspektren für die beiden Münzmetalle, Silber und Kupfer, auf Subnanometerskala bei Anlagerung von Wasserstoff einstellt. Dazu werden die Cluster aus Kupfer und Silber künstlich erzeugt, nach Masse getrennt, und mittels Photoelektronenspektroskopie untersucht.<br />Die Besonderheit der Bindung von Wasserstoff an Aluminiumnanoteilchen stellte eine Veröffentlichung von Li et al. dar: Aluminiumcluster bilden mit Wasserstoff gemäß den Wade-Mingos-Regeln Verbindungen ähnlich den Boranen. Im Verlauf dieser Arbeit wird gezeigt, welchen Einfluß auf das Photoelektronenspektrum ein Austausch von Wasserstoff gegen sein Isotop Deuterium hat.<br />Um die oben genannten Systeme zu untersuchen, wurde ein komplett neues Experiment aus den drei notwendigen Komponenten der Clusterphysik aufgebaut: einer Clusterquelle (Erzeugung), einem Flugzeitmassenspektrometer (Massentrennung) und einem Photoelektronenspektrometer (Untersuchung). | deu |
