Phys. Rev. A 58, 1162–1165 (1998)Ab initio molecular treatment of charge transfer by Si4+ ions in heliumReceived 5 March 1998; published in the issue dated August 1998 Ab initio potential-energy curves and coupling matrix elements of the 1,3Σ and 1,3Π molecular states involved in the collision of the Si4+ multicharged ion on helium have been determined by means of configuration-interaction methods. The total and partial electron capture cross sections have been determined using a semiclassical approach in the 2-eV–60-keV laboratory energy range. A sharp resonance has been exhibited for a 45.455-eV collision energy. © 1998 The American Physical Society URL:
