    Charge transfer of O2+ in helium at thermal and low electron volt energies (1993)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 99 (1993), S. 4495-4499

    Notes: Cross sections and rate coefficients in the thermal-eV energy range are calculated for the charge transfer reaction of O2+(3P) ions with helium. In agreement with earlier predictions, it is confirmed that the reaction populates preferentially the metastable (2P) state of the O+ ion. The computed cross sections are, however, considerably larger than previous experimental and theoretical estimations. A discussion is given of the reasons for this discrepancy.

    Notes: Abstract.  Ab initio potential-energy curves and coupling matrix elements of the Σ and Π molecular states involved in the collision of the Si2+, Si3+ and Si4+ multicharged ions on atomic hydrogen and helium have been determined by means of configuration interaction methods. The total and partial electron capture cross sections have been determined using a semiclassical or a quantal approach in the 0.002–0.1 au velocity range. A detailed comparison with very recent theoretical and experimental rate coefficient results is made.

    Charge transfer in S2++H collisions at intermediate energy (1993)

    Notes: Abstract Partial cross-sections for the charge transfer process of S2+ ions in collision with atomic hydrogen at impact energies up to 8 keV have been calculated by means of a semi-classical method using ab initio potential energy curves and couplings. The results are in relatively good agreement with experiment and improve significantly previous Landau-Zener calculations.

    Notes: Partial cross sections of single-electron capture on the n = 3 levels have been determined theoretically for the N5+ + He and O6+ + He collisions by means of a semiclassical method using ab initio potential energy curves and radial and rotational coupling matrix elements. The different behavior of these two isoelectronic systems is fairly well reproduced by our calculations.

    Notes: A full theoretical treatment of electron capture processes using ab initio configuration interaction methods within, according to the collision energy range concerned, a semiclassical or a quantal collisional formalism including translation effects has been developed recently. An application for collisions involving boron, an important impurity in fusion reactors, is presented on examples of the ground state: B3+(1s2) + He, B4+(1s) + H, and the metastable ion B3+(1s2s) + H reactions. © 1996 John Wiley & Sons, Inc.
