Abstract
Studies the single and double electron capture from helium atoms by 3He2+ ions with energies between 10 and 100 keV. The authors use a molecular approximation in which the electronic state of the system is expanded in terms of a linear combination of products of orbitals representing the state of a single electron in the field of two bare nuclei (OEDM orbitals). The electron-electron forces are incorporated in the theory as a coupling term in the equation describing the dynamics of the collision problem. Results are presented for the total cross sections and for the charge-exchange probabilities at a fixed scattering angle.Keywords
