1. 1. Experiments on mutual neutralization using storage rings with merged ion beams

   Författare :Gustav Eklund; Henning T Schmidt; Henrik Cederquist; Ansgar Simonsson; Daniel W. Savin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mutual neutralization; storage rings; merged beams; fysik; Physics;

   Sammanfattning : This thesis presents work on merged-beams experiments using the DESIREE facility, which consists of two electrostatic ion-storage rings operated at cryogenic temperatures of about 13 K. The two storage rings have a common straight section, where oppositely charged ions can interact at sub-eV collision energies. LÄS MER

3. 2. Recombination and ionization of astrophysically abundant ions

   Sammanfattning : The electron-ion recombination and electron-impact ionization of several astrophysically abundant C, N, O, and Ni ions have been investigated using the synchrotron storage ring CRYRING. The recombination rate coefficients predominanty used in the analyses of emission line spectra and for ionization balance calculations are determined from isoelectronic fits and extrapolations of theoretical and limited experimental results available from the literature.
