3. 2. Electronic states of adsorbates and insulating overlayers on metal surfaces

   Författare :Fredrik Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shockley surface states; local density of states; scanning tunneling microscope; chemisorption; sodium chloride; noble metals; image states; electronic states; density functional theory;

   Sammanfattning : Electronic states of adsorbates and insulating overlayers provide a wealth of scientifically interesting phenomena with great technological importance. Interesting phenomena arise, for example, from the interaction of electronic states of an adsorbate with the continuum of metal electron states, both propagating bulk states and surface states.

4. 3. Autoionizing states and their relevance in electron-ion recombination

   Författare :Dragan Nikolić; Eva Lindroth; Gleb Gribakin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron-ion recombination; Autoionization; Electron correlation calculations; Doubly excited states; Relativistic many-body perturbation theory; Coupled-cluster methodology; Intruder state problem; Physics; Fysik;

   Sammanfattning : Atomic physics plays an important role in determining the evolution stages in a wide range of laboratory and cosmic plasmas. Therefore, the main contribution to our ability to model, infer and control plasma sources is the knowledge of underlying atomic processes. LÄS MER

7. 5. Electron Recombination with Small Molecular Ions

   Författare :Johanna Brinne Roos; Hans Ågren; Åsa Larson; Hans Karlsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissociative recombination; ion-pair formation; resonant states; wave packet; molecular dynamics; electron scattering; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : In this thesis I have theoretically studied electron recombination processes with small molecular ions. In these kind of processes resonant states are involved. To calculate the potential energy for these states as a function of internuclear distance, structure calculations and scattering calculations have to be performed. LÄS MER
