Charge transfer recombination of Si2+ ions from atomic hydrogen Original Research Article

Ab-initio potential energy curves and coupling matrix elements of the molecular states involved in the collision of the Si2+ multicharged ion on atomic hydrogen have been determined by means of configuration interaction methods. The total and partial electron capture cross sections have been determined using a semi-classical approach in the 0.1–1000 eV center-of-mass energy range. The results are in fair agreement with previous works and show the influence of radial, rotational as well as translational effects.
