In this work two investigations are carried out with this method: Employing conventional PES, photoelectron spectra of Silicon clusters with up to 50 atoms are recorded at a high photon energy of 6.4 eV. These are the first PES spectra of Sin-anions with more than 13 atoms at this photon energy. The data for Si8- to Si20- is compared to theoretical predictions which allowed conclusions for the ground state geometries of the anions. These results represent the first spectroscopic evidence for the postulated tricapped trigonal prism growth pattern of Silicon clusters in this range of sizes. This investigation represents a further step in understanding the properties of small silicon particles. In the second part of this thesis PES is employed in the form of time resolved photoemission (TRPE). This method, experimentally closely related to conventional PES, allows the observation of ultra fast dynamic processes in molecules and clusters, like the dissociation of a particle or the decay of an electronic excitation. The decay of an electronically excited state of the C3- anion was observed. The related electronic processes were identified and assigned to the participating electronic states. The lifetime of the excited state was determined by the analysis of the temporal development of the system. This measurement displays the potential this spectroscopic method provides in the investigation of small particles and clusters.</dcterms:abstract> <dcterms:hasPart rdf:resource=""/> <dcterms:isPartOf rdf:resource=""/> <dc:language>deu</dc:language> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:available rdf:datatype="">2011-03-24T14:53:59Z</dcterms:available> </rdf:Description> </rdf:RDF>
