  2. 12. Ways of determining and characterising resonances in scattering processes

    Author : Ksenia Shilyaeva; Nils Elander; Dage Sundholm; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; quantum scattering theory; complex scaling; resonances; Molecular physics; Molekylfysik; Physics; fysik;

    Abstract : Scattering cross sections very often display structures. To clarify if these structures correspond to resonances one has to check if they are poles of the scattering matrix (S-matrix) in the fourth quadrant of the complex momentum plane. Furthermore, the states corresponding to these poles also need to have an appropriate scattering amplitude. READ MORE

  3. 13. Quantum Wavepacket Dynamics in Molecular and Trapped Ion Systems

    Author : Dong Wang; Tony Hansson; Volker Engel; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; wavepacket; revival; anisotropy; polarization; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Abstract : The motions of a wavepacket in the two coupled potentials studied in this thesis can be classified into either bistable or astable motion according to the wavepacket interference at the curve crossing. Bistable motion, in which the wavepacket performs a coupled oscillation but remains in the same adiabatic and diabatic state, can exist both in bound-bound systems and bound-unbound ones with long time stability.

  4. 14. Dynamics in the Dissociative Recombination of Small Polyatomic Molecular Ions

    Author : Vitali Zhaunerchyk; Richard Thomas; Xavier Urbain; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dissociative recombination; Molecular physics; Molekylfysik; Physics; fysik;

    Abstract : Dissociative recombination (DR) is a process in which a positive molecular ion recombines with an electron and subsequently dissociates into neutral fragments. Among the different types of molecular ion-electron reactions DR deserves particular attention due to the important role it plays in low-temperature and low-density plasmas. READ MORE
