  2. 1. Electron Recombination with Small Molecular Ions

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

    Abstract : 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. READ MORE

  4. 2. Reaction dynamics on highly excited states

    Author : Johanna Brinne Roos; Åsa Larson; Ioan F. Schneider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio calculations; dissociative recombination; resonant ion-pair formation; mutual neutralization; molecular electronic states; molecule-electron collisions; quantum chemistry; molecular dynamics; Chemical physics; Kemisk fysik; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Abstract : In this thesis I have performed theoretical studies on the reaction dynamics in few-atom molecules. In particular, I have looked at reaction processes in which highly excited resonant states are involved. READ MORE

  5. 3. Electron impact dissociation of molecular ions at CRYRING

    Author : Ahmed Al-Khalili; Ronald A Phaneuf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : In this thesis, the electron impact dissociation of molecular ions has been studied using the ion storage ring CRYRING at Manne Siegbahn Laboratory in Stockholm, Sweden. The electron impact dissociation of molecular ions occurs via many processes, which lead to different charge states of the product fragments. READ MORE

  6. 4. Theoretical studies of collisions involving the H2 reaction complex

    Author : Johan Hörnquist; Åsa Larson; Eva Lindroth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : In this thesis, collisions involving the H2 reaction complex are studied theoretically and the processes considered are mutual neutralization, double charge transfer, associative ionization, dissociative recombination and resonant ion-pair formation. These processes are examples of reactions that involve several excited states and where the Born-Oppenheimer approximation is not applicable. READ MORE
