1. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions
Abstract : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. READ MORE

2. Molecular beam study of non-adiabatic electron transfer in the Cl2+Ksurf surface reaction
Abstract : Halogen molecules impinging on alkali metal surfaces constitute model systems for studies of charge transfer, dissociation dynamics and non-adiabatic energy dissipation in molecule-surface reactions. This thesis reports emission of exo-electrons and photons from the surface as a result of strong non-adabaticity in the Cl2 gas on K$^{solid}$ reaction. READ MORE

3. Dynamics of Molecular Adsorption on Metal Surfaces
Abstract : In this Thesis different aspects of dissociative chemisorption and of scattering and trapping in a physisorption potential are investigated, mainly by means of classical trajectory calculations. In papers I-III the sticking coefficients of hydrogen on copper and nickel are calculated using a multidimensional effective-medium potential which takes the molecular orientation as well as the surface structure into account.

4. Model Studies of Electron Transfer and Reaction Dynamics at Surfaces
Abstract : Charge-transfer is of key importance in many physical, chemical and biological processes, including surface reactions. This thesis consists of several theories for and model studies of surface reactions that are initiated by electron transfer between the surface to a molecule. READ MORE

5. Elementary Surface Processes on Graphite and Aluminium
Abstract : Molecular processes on solid surfaces are of fundamental and technological importance. This work focuses on various reactive processes on a carbon (graphite(0001)) surface, and on the initial oxygen interaction with an aluminium (Al(111)) surface. READ MORE
