CHARGE-TRANSFER RECOMBINATION OF SI2-HYDROGEN( IONS FROM ATOMIC)

Ab-initio potential energy curves and coupling matrix elements of the molecular states involved in the collision of the Si2+ multicharged io n on atomic hydrogen have been determined by means of configuration in teraction methods. The total and partial electron capture cross sectio ns have been determined using a semi-classical approach in the 0.1-100 0 eV center-of-mass energy range. The results are in fair agreement wi th previous works and show the influence of radial, rotational as well as translational effects. (C) 1998 Elsevier Science B.V. All rights r eserved.
